Struct TimerSubsystem

pub struct TimerSubsystem { /* private fields */ }

Available on crate feature dep_sdl2 only.

Implementations

impl TimerSubsystem

pub fn sdl(&self) -> Sdl

Obtain an SDL context.

impl TimerSubsystem

pub fn add_timer<'b, 'c>( &'b self, delay: u32, callback: Box<dyn FnMut() -> u32 + Send + 'c>, ) -> Timer<'b, 'c>

Constructs a new timer using the boxed closure callback.

The timer is started immediately, it will be cancelled either:

• when the timer is dropped
• or when the callback returns a non-positive continuation interval

The callback is run in a thread that is created and managed internally by SDL2 from C. The callback must not panic!

pub fn ticks(&self) -> u32

Gets the number of milliseconds elapsed since the timer subsystem was initialized.

It’s recommended that you use another library for timekeeping, such as time.

This function is not recommended in upstream SDL2 as of 2.0.18 and internally calls the 64-bit variant and masks the result.

pub fn ticks64(&self) -> u64

Gets the number of milliseconds elapsed since the timer subsystem was initialized.

It’s recommended that you use another library for timekeeping, such as time.

pub fn delay(&self, ms: u32)

Sleeps the current thread for the specified amount of milliseconds.

It’s recommended that you use std::thread::sleep() instead.

pub fn performance_counter(&self) -> u64

pub fn performance_frequency(&self) -> u64
