Struct FrameRate 

pub struct FrameRate { /* private fields */ }

A positive rational frame rate in reduced form, at most one frame per tick (120 000 frames per second).

Implementations

impl FrameRate

pub const fn new(num: u32, den: u32) -> Result<Self, FrameRateError>

Creates and reduces a positive rate.

Errors

Returns an error for zero components or sub-tick frame duration.

pub const fn numerator(self) -> u32

Reduced numerator.

pub const fn denominator(self) -> u32

Reduced denominator.

pub fn frame_start(self, frame: i64) -> Option<MediaTime>

Exact floored start of a signed frame index, or None when it lies outside the i64 tick range.

pub fn frame_at_or_before(self, time: MediaTime) -> Option<i64>

Frame whose half-open interval contains time, or None when the index does not fit in an i64.
