Struct wasm_stopwatch::Stopwatch

pub struct Stopwatch { /* fields omitted */ }

Implementations

impl Stopwatch

A stopwatch which tracks time in seconds.

pub fn new() -> Self

Creates a new stopwatch with the current time set to 0.

pub fn with_speed(speed: f64) -> Self

Creates a stopwatch which advances the given amount every second.

For instance, Stopwatch::with_speed(1.0/60.0) creates a stopwatch which uses minutes as the time unit instead of seconds.

pub fn paused(&self) -> bool

Returns whether the stopwatch is paused.

pub fn pause(&mut self)

Pauses the stopwatch. If the stopwatch was already paused, this does nothing.

pub fn unpause(&mut self)

Unpauses the stopwatch. If the stopwatch was already unpaused, this does nothing.

pub fn toggle_pause(&mut self)

Toggles whether the stopwatch is paused.

pub fn get_time(&self) -> f64

Gets the current time.

pub fn set_time(&mut self, cur_time: f64)

Sets the current time.

pub fn reset(&mut self)

Resets the stopwatch to zero.

pub fn add_time(&mut self, time_diff: f64)

Advances the stopwatch by time_diff.

pub fn sleep_until(&self, time: f64)

Sleeps until this stopwatch reaches the given time. May sleep for slightly longer than requested (the same behavior as std::thread::sleep), so in practice most games should use vsync or similar mechanisms instead of using this to maintain a certain frame rate.

Panics if the stopwatch is paused.

Trait Implementations

impl Clone for Stopwatch

pub fn clone(&self) -> Stopwatch

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Stopwatch

pub fn default() -> Self

Returns the "default value" for a type.
