Struct LambdaInvocationOutput 

pub struct LambdaInvocationOutput {
    pub payload: Vec<u8>,
    pub function_error: Option<String>,
}

What a synchronous Lambda invocation produced: the response payload and, when the function failed, the X-Amz-Function-Error value. This is the signal real Lambda gives (Invoke still returns 200); integrations must branch on function_error, never on the payload’s shape, because a function may legitimately return an object carrying errorType / errorMessage, and some failures (a timeout reported without an errorType by older runtimes) carry only one of them.

Fields

payload: Vec<u8>

The response payload. For a function error this is the error object ({"errorType", "errorMessage", ...}) the runtime reported.

function_error: Option<String>

Some("Unhandled") when the invocation produced a function error.

Implementations

impl LambdaInvocationOutput

pub fn success(payload: impl Into<Vec<u8>>) -> Self

A successful invocation that returned payload.

pub fn unhandled(payload: impl Into<Vec<u8>>) -> Self

An invocation that failed with a function error reported as payload.

pub fn is_function_error(&self) -> bool

True when the function failed (X-Amz-Function-Error was set).

pub fn error_type(&self) -> Option<String>

The error object’s errorType, for a function error whose payload names one. None for a success or an error payload without a type.

pub fn error_message(&self) -> Option<String>

The error object’s errorMessage, for a function error whose payload carries one.
