Expand description
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.

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

, or
InterceptorContext::output_or_error
MAY be available.
If the operation succeeded, the output

pieces of information may be available depending on where in the operation lifecycle it failed.

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
.

A hook called when an execution is completed.
When: This will ALWAYS be called once per execution. The duration

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.
