Enum MainLoopTiming

pub enum MainLoopTiming {
    SetTimeout(c_int),
    RequestAnimationFrame(c_int),
    SetImmediate,
}

Parameters of the main loop’s scheduling mode.

While emscripten implements this using 2 int variables: mode and value; we put here only the valid modes.

Variants

SetTimeout(c_int)

The main loop function gets called periodically using setTimeout(), with the payload being the interval between the calls of setTimeout().

RequestAnimationFrame(c_int)

The main loop function gets called using requestAnimationFrame(), with the payload being the “swap interval” rate for the main loop:

• if the payload is 1, the loop function gets called at every vsync (60fps for the common 60Hz display, 120fps for a 120Hz display, etc.),
• if the payload is 2, the loop function gets called every second vsync (that usually means 30fps, depends on the display),
• in general, the rate is {display frequency}/{the payload} fps.

SetImmediate

The main loop function gets called using setImmediate(), a function only available in Legacy Edge and partially in node.js. While the said function can be emulated using postMessage(), this mode of running the main loop is discouraged by the Emscripten devs.

Trait Implementations

impl Clone for MainLoopTiming

fn clone(&self) -> MainLoopTiming

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MainLoopTiming

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MainLoopTiming

fn eq(&self, other: &MainLoopTiming) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
