Struct Timer 

pub struct Timer { /* private fields */ }

Software timer with a safe Rust callback.

The timer stores a function pointer and generates an internal trampoline so the user callback is a plain fn() — no unsafe, no raw pointers.

Implementations

impl Timer

pub fn new(callback: fn(), period_ms: u32, one_shot: bool) -> Result<Self>

Create a new timer via heap allocation (only in heap mode).

• callback — safe Rust function called each time the timer fires.
• period_ms — timer period in milliseconds.
• one_shot — if true, the timer fires once and stops.

pub fn create( storage: &'static TimerStorage, callback: fn(), period_ms: u32, one_shot: bool, ) -> Result<Self>

Mode-agnostic constructor (see crate::Mutex::create). Heap mode ignores storage; zero-heap mode backs the timer with it.

pub fn start(&self) -> Result<()>

Start the timer, beginning countdown from now.

Errors

Returns an error if the underlying RTOS call fails.

pub fn stop(&self) -> Result<()>

Stop the timer, preventing further callbacks until restarted.

Errors

Returns an error if the underlying RTOS call fails.

pub fn reset(&self) -> Result<()>

Reset the timer, restarting the period from now.

If the timer is stopped, this also starts it.

Errors

Returns an error if the underlying RTOS call fails.
