Struct lambda_runtime::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,
}

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)

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

impl Context

pub fn with_config(self, config: &Config) -> Self

Add environment details to the context by setting env_config.

pub fn deadline(&self) -> SystemTime

The execution deadline for the current invocation.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Context

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<Context> for Context

fn eq(&self, other: &Context) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Context

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<HeaderMap<HeaderValue>> for Context

type Error = Box<dyn Error + Send + Sync + 'static, Global>

The type returned in the event of a conversion error.

fn try_from(headers: HeaderMap) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Context

impl StructuralEq for Context

impl StructuralPartialEq for Context
