Struct aws_runtime::recursion_detection::RecursionDetectionInterceptor

#[non_exhaustive]
pub struct RecursionDetectionInterceptor { /* private fields */ }

Recursion Detection Interceptor

This interceptor inspects the value of the AWS_LAMBDA_FUNCTION_NAME and _X_AMZN_TRACE_ID environment variables to detect if the request is being invoked in a Lambda function. If it is, the X-Amzn-Trace-Id header will be set. This enables downstream services to prevent accidentally infinitely recursive invocations spawned from Lambda.

Implementations

impl RecursionDetectionInterceptor

pub fn new() -> Self

Creates a new RecursionDetectionInterceptor

Trait Implementations

impl Debug for RecursionDetectionInterceptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RecursionDetectionInterceptor

fn default() -> RecursionDetectionInterceptor

Returns the “default value” for a type.

impl Intercept for RecursionDetectionInterceptor

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

fn modify_before_signing( &self, context: &mut BeforeTransmitInterceptorContextMut<'_>, _runtime_components: &RuntimeComponents, _cfg: &mut ConfigBag, ) -> Result<(), BoxError>

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

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.

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.

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.

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

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

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

A hook called before the retry loop is entered. This method has the ability to modify and return a new transport request message of the same type, except when a failure occurs earlier in the request pipeline.

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

A hook called before each attempt at sending the transmission request message to the service.

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

A hook called before the transport request message is signed.

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

A hook called after the transport request message is signed.

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

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

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

A hook called before the transport request message is sent to the service.

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

A hook called after the transport request message is sent to the service and a transport response message is received.

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

A hook called before the transport response message is unmarshalled. This method has the ability to modify and return a new transport response message of the same type.

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

A hook called before the transport response message is unmarshalled

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

A hook called after the transport response message is unmarshalled.

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.

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.
