Type Alias TimerParam 

pub type TimerParam = Arc<dyn Any + Send + Sync>;

All OSAL trait definitions for advanced usage. Type-erased parameter for timer callbacks.

Allows passing arbitrary data to timer callback functions in a type-safe manner. The parameter is wrapped in an Arc for safe sharing and can be downcast to its original type.

Thread Safety

The inner type must implement Any + Send + Sync since timer callbacks execute in the timer service task context.

Examples

use osal_rs::os::*;
use std::sync::Arc;

// Create a parameter
let param: TimerParam = Arc::new(7u32);

// In the timer callback, downcast to access it
let count = param.downcast_ref::<u32>().copied();
assert_eq!(count, Some(7));

// A downcast to the wrong type simply reports `None`.
assert!(param.downcast_ref::<i8>().is_none());

Aliased Type

pub struct TimerParam { /* private fields */ }
