Timer abstraction for different hardware timers.

Required Methods

unsafe fn init(&mut self, config: &TimerConfig) -> Result<(), TimerError>

Initialize the timer with the given configuration.

Safety

This function configures hardware timers and interrupt vectors. It must only be called once during system initialization with interrupts disabled.

fn start(&mut self) -> Result<(), TimerError>

Start the timer.

The timer will begin generating interrupts at the configured frequency.

fn stop(&mut self) -> Result<(), TimerError>

Stop the timer.

This stops interrupt generation but preserves timer configuration.

fn current_count(&self) -> u64

Get the current timer count.

This provides access to the hardware timer’s current count value for high-precision timing measurements.

fn counts_to_nanos(&self, counts: u64) -> u64

Convert timer counts to nanoseconds.

fn nanos_to_counts(&self, nanos: u64) -> u64

Convert nanoseconds to timer counts.

fn set_oneshot(&mut self, duration: Duration) -> Result<(), TimerError>

Set up a one-shot timer for the given duration.

This is used for implementing sleep and timeout functionality.
