An interceptor allows injecting code into the SDK ’s request execution pipeline.

Terminology:

• An execution is one end-to-end invocation against an SDK client.
• An attempt is an attempt at performing an execution. By default executions are retried multiple times based on the client ’s retry strategy.
• A hook is a single method on the interceptor, allowing injection of code into a specific part of the SDK ’s request execution pipeline. Hooks are either “read” hooks, which make it possible to read in-flight request or response messages, or “read/write” hooks, which make it possible to modify in-flight request or output messages.

Required Methods

fn name(&self) -> &'static str

The name of this interceptor, used in error messages for debugging.

Provided Methods

fn read_before_execution( &self, context: &BeforeSerializationInterceptorContextRef<'_>, cfg: &mut ConfigBag, ) -> Result<(), Box<dyn Error + Sync + Send>>

A hook called at the start of an execution, before the SDK does anything else.

When: This will ALWAYS be called once per execution. The duration between invocation of this hook and after_execution is very close to full duration of the execution.

Available Information: The InterceptorContext::input is ALWAYS available. Other information WILL NOT be available.

Error Behavior: Errors raised by this hook will be stored until all interceptors have had their before_execution invoked. Other hooks will then be skipped and execution will jump to modify_before_completion with the raised error as the InterceptorContext::output_or_error. If multiple before_execution methods raise errors, the latest will be used and earlier ones will be logged and dropped.

fn modify_before_serialization( &self, context: &mut BeforeSerializationInterceptorContextMut<'_>, runtime_components: &RuntimeComponents, cfg: &mut ConfigBag, ) -> Result<(), Box<dyn Error + Sync + Send>>

A hook called before the input message is marshalled into a transport message. This method has the ability to modify and return a new request message of the same type.

When: This will ALWAYS be called once per execution, except when a failure occurs earlier in the request pipeline.

Available Information: The InterceptorContext::input is ALWAYS available. This request may have been modified by earlier modify_before_serialization hooks, and may be modified further by later hooks. Other information WILL NOT be available.

Error Behavior: If errors are raised by this hook, execution will jump to modify_before_completion with the raised error as the InterceptorContext::output_or_error.

Return Constraints: The input message returned by this hook MUST be the same type of input message passed into this hook. If not, an error will immediately be raised.

fn read_before_serialization( &self, context: &BeforeSerializationInterceptorContextRef<'_>, runtime_components: &RuntimeComponents, cfg: &mut ConfigBag, ) -> Result<(), Box<dyn Error + Sync + Send>>

A hook called before the input message is marshalled into a transport message.

When: This will ALWAYS be called once per execution, except when a failure occurs earlier in the request pipeline. The duration between invocation of this hook and after_serialization is very close to the amount of time spent marshalling the request.

Available Information: The InterceptorContext::input is ALWAYS available. Other information WILL NOT be available.

Error Behavior: If errors are raised by this hook, execution will jump to modify_before_completion with the raised error as the InterceptorContext::output_or_error.

Available Information: The InterceptorContext::request is ALWAYS available. Other information WILL NOT be available.

Error Behavior: If errors are raised by this hook, execution will jump to modify_before_completion with the raised error as the InterceptorContext::output_or_error.

When: This will ALWAYS be called once per attempt, except when a failure occurs earlier in the request pipeline. This method may be called multiple times in the event of retries. The duration between invocation of this hook and after_deserialization is very close to the amount of time spent unmarshalling the service response. Depending on the protocol and operation, the duration may include the time spent downloading the response data.

Available Information: The InterceptorContext::response is ALWAYS available. Other information WILL NOT be available. In the event of retries, the InterceptorContext will not include changes made in previous attempts (e.g. by request signers or other interceptors).

Error Behavior: If errors are raised by this hook, execution will jump to modify_before_attempt_completion with the raised error as the InterceptorContext::output_or_error.

fn modify_before_attempt_completion( &self, context: &mut FinalizerInterceptorContextMut<'_>, runtime_components: &RuntimeComponents, cfg: &mut ConfigBag, ) -> Result<(), Box<dyn Error + Sync + Send>>

A hook called when an attempt is completed. This method has the ability to modify and return a new output message or error matching the currently-executing operation.

When: This will ALWAYS be called once per attempt, except when a failure occurs before before_attempt. This method may be called multiple times in the event of retries.

Available Information: The InterceptorContext::input, InterceptorContext::request, InterceptorContext::response, or InterceptorContext::output_or_error MAY be available. If the operation succeeded, the output will be available. Otherwise, any of the other pieces of information may be available depending on where in the operation lifecycle it failed. In the event of retries, the InterceptorContext will not include changes made in previous attempts (e.g. by request signers or other interceptors).

Error Behavior: If errors are raised by this hook, execution will jump to after_attempt with the raised error as the InterceptorContext::output_or_error.

Return Constraints: Any output message returned by this hook MUST match the operation being invoked. Any error type can be returned, replacing the response currently in the context.

fn read_after_attempt( &self, context: &FinalizerInterceptorContextRef<'_>, runtime_components: &RuntimeComponents, cfg: &mut ConfigBag, ) -> Result<(), Box<dyn Error + Sync + Send>>

A hook called when an attempt is completed.

When: This will ALWAYS be called once per attempt, as long as before_attempt has been executed.

Available Information: The InterceptorContext::input, InterceptorContext::request, InterceptorContext::response, or InterceptorContext::output_or_error MAY be available. If the operation succeeded, the output will be available. Otherwise, any of the other pieces of information may be available depending on where in the operation lifecycle it failed. In the event of retries, the InterceptorContext will not include changes made in previous attempts (e.g. by request signers or other interceptors).

Error Behavior: Errors raised by this hook will be stored until all interceptors have had their after_attempt invoked. If multiple after_execution methods raise errors, the latest will be used and earlier ones will be logged and dropped. If the retry strategy determines that the execution is retryable, execution will then jump to before_attempt. Otherwise, execution will jump to modify_before_attempt_completion with the raised error as the InterceptorContext::output_or_error.

fn modify_before_completion( &self, context: &mut FinalizerInterceptorContextMut<'_>, runtime_components: &RuntimeComponents, cfg: &mut ConfigBag, ) -> Result<(), Box<dyn Error + Sync + Send>>

A hook called when an execution is completed. This method has the ability to modify and return a new output message or error matching the currently - executing operation.

When: This will ALWAYS be called once per execution.

Available Information: The InterceptorContext::input, InterceptorContext::request, InterceptorContext::response, or InterceptorContext::output_or_error MAY be available. If the operation succeeded, the output will be available. Otherwise, any of the other pieces of information may be available depending on where in the operation lifecycle it failed. In the event of retries, the InterceptorContext will not include changes made in previous attempts (e.g. by request signers or other interceptors).

Error Behavior: If errors are raised by this hook , execution will jump to after_attempt with the raised error as the InterceptorContext::output_or_error.

Return Constraints: Any output message returned by this hook MUST match the operation being invoked. Any error type can be returned , replacing the response currently in the context.

fn read_after_execution( &self, context: &FinalizerInterceptorContextRef<'_>, runtime_components: &RuntimeComponents, cfg: &mut ConfigBag, ) -> Result<(), Box<dyn Error + Sync + Send>>

A hook called when an execution is completed.

When: This will ALWAYS be called once per execution. The duration between invocation of this hook and before_execution is very close to the full duration of the execution.

Available Information: The InterceptorContext::input, InterceptorContext::request, InterceptorContext::response, or InterceptorContext::output_or_error MAY be available. If the operation succeeded, the output will be available. Otherwise, any of the other pieces of information may be available depending on where in the operation lifecycle it failed. In the event of retries, the InterceptorContext will not include changes made in previous attempts (e.g. by request signers or other interceptors).

Error Behavior: Errors raised by this hook will be stored until all interceptors have had their after_execution invoked. The error will then be treated as the InterceptorContext::output_or_error to the customer. If multiple after_execution methods raise errors , the latest will be used and earlier ones will be logged and dropped.
