Struct CallbackOptions 

pub struct CallbackOptions { /* private fields */ }

Configure callback timeout behavior.

Provide a builder-style API for configuring callback operations. By default, no timeouts are set — the callback remains active indefinitely until an external system signals success or failure.

Examples

use durable_lambda_core::types::CallbackOptions;

// No timeouts (default).
let opts = CallbackOptions::new();

// 5-minute overall timeout, 30-second heartbeat timeout.
let opts = CallbackOptions::new()
    .timeout_seconds(300)
    .heartbeat_timeout_seconds(30);

Implementations

impl CallbackOptions

pub fn new() -> CallbackOptions

Create a new CallbackOptions with no timeouts configured.

Examples

use durable_lambda_core::types::CallbackOptions;

let opts = CallbackOptions::new();

pub fn timeout_seconds(self, seconds: i32) -> CallbackOptions

Set the overall timeout in seconds for the callback.

If no success/failure signal arrives before this deadline, the server marks the callback as timed out. Must be a positive value. To use no timeout, omit this setter entirely.

Panics

Panics if seconds is 0 or negative.

Examples

use durable_lambda_core::types::CallbackOptions;

let opts = CallbackOptions::new().timeout_seconds(300);

pub fn heartbeat_timeout_seconds(self, seconds: i32) -> CallbackOptions

Set the heartbeat timeout in seconds.

External systems must send periodic heartbeat signals within this interval to keep the callback alive. Must be a positive value. To use no heartbeat requirement, omit this setter entirely.

Panics

Panics if seconds is 0 or negative.

Examples

use durable_lambda_core::types::CallbackOptions;

let opts = CallbackOptions::new().heartbeat_timeout_seconds(30);

pub fn get_timeout_seconds(&self) -> i32

Return the configured timeout in seconds.

Examples

use durable_lambda_core::types::CallbackOptions;

let opts = CallbackOptions::new();
assert_eq!(opts.get_timeout_seconds(), 0);

let opts = CallbackOptions::new().timeout_seconds(300);
assert_eq!(opts.get_timeout_seconds(), 300);

pub fn get_heartbeat_timeout_seconds(&self) -> i32

Return the configured heartbeat timeout in seconds.

Examples

use durable_lambda_core::types::CallbackOptions;

let opts = CallbackOptions::new();
assert_eq!(opts.get_heartbeat_timeout_seconds(), 0);

let opts = CallbackOptions::new().heartbeat_timeout_seconds(30);
assert_eq!(opts.get_heartbeat_timeout_seconds(), 30);
