Struct image::Delay

pub struct Delay { /* fields omitted */ }

The delay of a frame relative to the previous one.

Methods

impl Delay

pub fn from_numer_denom_ms(numerator: u32, denominator: u32) -> Self

Create a delay from a ratio of milliseconds.

Examples

use image::Delay;
let delay_10ms = Delay::from_numer_denom_ms(10, 1);

pub fn from_saturating_duration(duration: Duration) -> Self

Convert from a duration, clamped between 0 and an implemented defined maximum.

The maximum is at least i32::MAX milliseconds. It should be noted that the accuracy of the result may be relative and very large delays have a coarse resolution.

Examples

use std::time::Duration;
use image::Delay;

let duration = Duration::from_millis(20);
let delay = Delay::from_saturating_duration(duration);

pub fn numer_denom_ms(self) -> (u32, u32)

The numerator and denominator of the delay in milliseconds.

This is guaranteed to be an exact conversion if the Delay was previously created with the from_numer_denom_ms constructor.

Trait Implementations

impl Clone for Delay

fn clone(&self) -> Delay
