Struct lambda_http::Context

#[non_exhaustive]
pub struct Context { pub request_id: String, pub deadline: u64, pub invoked_function_arn: String, pub xray_trace_id: Option<String>, pub client_context: Option<ClientContext>, pub identity: Option<CognitoIdentity>, pub env_config: Config, }
Expand description

The Lambda function execution context. The values in this struct are populated using the Lambda environment variables and the headers returned by the poll request to the Runtime APIs.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§request_id: String

The AWS request ID generated by the Lambda service.

§deadline: u64

The execution deadline for the current invocation in milliseconds.

§invoked_function_arn: String

The ARN of the Lambda function being invoked.

§xray_trace_id: Option<String>

The X-Ray trace ID for the current invocation.

§client_context: Option<ClientContext>

The client context object sent by the AWS mobile SDK. This field is empty unless the function is invoked using an AWS mobile SDK.

§identity: Option<CognitoIdentity>

The Cognito identity that invoked the function. This field is empty unless the invocation request to the Lambda APIs was made using AWS credentials issues by Amazon Cognito Identity Pools.

§env_config: Config

Lambda function configuration from the local environment variables. Includes information such as the function name, memory allocation, version, and log streams.

Implementations§
