Struct FrameRate 

pub struct FrameRate { /* private fields */ }

A positive rational number of frames per second, stored in reduced form.

Implementations

impl FrameRate

pub const NTSC_FILM: Self

Film rate of exactly 24000/1001 frames per second.

pub const NTSC: Self

NTSC rate of exactly 30000/1001 frames per second.

pub const NTSC_DOUBLE: Self

Double NTSC rate of exactly 60000/1001 frames per second.

pub fn try_new( numerator: u32, denominator: u32, ) -> Result<Self, ValidationError>

Constructs and reduces a rational frame rate from runtime components.

Errors

Returns an error when either component is zero.

pub const fn new(numerator: NonZeroU32, denominator: NonZeroU32) -> Self

Constructs and reduces a rational frame rate.

pub const fn per_second(frames: NonZeroU32) -> Self

Constructs a rate of whole frames per second; see also fps!.

pub const fn numerator(self) -> u32

Returns the numerator of the reduced rate.

pub const fn denominator(self) -> u32

Returns the denominator of the reduced rate.

pub fn frame_duration(self) -> Duration

Returns the first frame’s duration, rounded up if not tick-exact. Use Time::from_frame for later boundaries to avoid accumulated rounding.
