Implementations

impl Invocation

pub fn new(payload: Value, timeout_ms: u64) -> Self

Creates a new invocation with default values.

Arguments

• payload - The JSON payload for this invocation
• timeout_ms - Timeout in milliseconds for this invocation

Returns

A new Invocation instance with generated IDs and timestamps.

Examples

use serde_json::json;
use lambda_simulator::invocation::Invocation;

let invocation = Invocation::new(json!({"key": "value"}), 3000);
assert!(!invocation.request_id.is_empty());

pub fn deadline_ms(&self) -> i64

Returns the deadline as milliseconds since Unix epoch.

This is used for the Lambda-Runtime-Deadline-Ms header.

Trait Implementations

impl Clone for Invocation

fn clone(&self) -> Invocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Invocation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Invocation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Invocation

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

where __S: Serializer,
