Enum LambdaInvokeMode 

pub enum LambdaInvokeMode {
    Buffered,
    ResponseStream,
}

Lambda function invoke mode.

Controls how Lambda handles the response from your function:

• LambdaInvokeMode::Buffered - Lambda buffers the entire response before returning it
• LambdaInvokeMode::ResponseStream - Lambda streams the response as it’s generated

Response Streaming

Response streaming is useful for:

• Server-Sent Events (SSE)
• Large file downloads
• Real-time data feeds
• Reducing time-to-first-byte (TTFB)

To use response streaming, you must also configure your Lambda function URL with InvokeMode: RESPONSE_STREAM.

Examples

use lambda_web_adapter::LambdaInvokeMode;

let buffered: LambdaInvokeMode = "buffered".into();
let streaming: LambdaInvokeMode = "response_stream".into();

assert_eq!(buffered, LambdaInvokeMode::Buffered);
assert_eq!(streaming, LambdaInvokeMode::ResponseStream);

Variants

Buffered

Buffered mode - Lambda buffers the entire response before returning. This is the default mode and works with all Lambda invocation methods.

ResponseStream

Response streaming mode - Lambda streams the response as it’s generated. Requires Lambda function URL with InvokeMode: RESPONSE_STREAM.

Trait Implementations

impl Clone for LambdaInvokeMode

fn clone(&self) -> LambdaInvokeMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LambdaInvokeMode

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

Formats the value using the given formatter.

impl Default for LambdaInvokeMode

fn default() -> LambdaInvokeMode

Returns the “default value” for a type.

impl From<&str> for LambdaInvokeMode

fn from(value: &str) -> Self

Converts to this type from the input type.

impl PartialEq for LambdaInvokeMode

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

Tests for self and other values to be equal, and is used by ==.

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

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