Struct dgews::timer::Timer

pub struct Timer { /* private fields */ }

Timer sturct to retrieve current time

Example

let mut timer = Timer::new();
println!("Time: {}", time.time());
 
std::time::sleep(Duration::from_secs(10));
time.update();
println!("Time: {}", time.time());

Implementations

impl Timer

pub fn new() -> Self

Creates a new instance of the Time struct

Example

let timer = Timer::new();

pub fn update(&mut self)

Updates the Timer struct’s time

Example

let mut timer = Timer::new();
 
std::time::sleep(Duration::from_secs(5));
 
timer.update();

pub fn dt(&mut self) -> f32

Retrieves the delta time. (dt() function updates the this instance as well)

Example

let mut timer = Timer::new();
std::time::sleep(Duration::from_secs(10));
timer.update();
std::time::sleep(Duration::from_secs(10));
println!("dt: {}", time.dt());

pub fn current_frame(&self) -> f32

Retrieves the last time when an instance was updated

Example

let mut timer = Timer::new();
assert_eq!(timer.current_frame(), 0.0);
 
std::time::sleep(Duration::from_secs(10));
assert_eq!(timer.current_frame(), 0.0);
 
timer.update();
assert_neq!(timer.current_frame(), 0.0);

pub fn time(&self) -> f32

Retrieves the exact current time

Example

let mut timer = Timer::new();
 
for _ in .. {
    println!("Current time: {}", timer.time());
}

Trait Implementations

impl Clone for Timer

fn clone(&self) -> Timer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Timer

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

Formats the value using the given formatter.

impl PartialEq<Timer> for Timer

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

This method tests for self and other values to be equal, and is used by ==.

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

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