Struct Timer 

pub struct Timer { /* private fields */ }

A tick counter.

Implementations

impl Timer

pub fn new() -> Timer

A timer starting at zero.

pub fn tick(&mut self)

Advances the counter by one, saturating at the top of the word range.

pub fn ticks(&self) -> i64

The current count.

pub fn compare(&self) -> i64

The value the count is compared against.

pub fn is_firing(&self) -> bool

True while the timer is asserting an interrupt.

Zero disarms, so a machine that never writes COMPARE is never interrupted. The test is >= rather than == so that a compare value already in the past fires at once instead of being missed.

Trait Implementations

impl Default for Timer

fn default() -> Timer

Returns the “default value” for a type.

impl Device for Timer

fn name(&self) -> &'static str

A name, used in error messages.

fn read(&mut self, offset: i64) -> Result<Tryte, MemoryError>

Reads one tryte. May have side effects.

fn write(&mut self, offset: i64, value: Tryte) -> Result<(), MemoryError>

Writes one tryte.
