Struct FrameRate 

pub struct FrameRate { /* private fields */ }

A frame rate represented as a fraction (numerator/denominator).

This allows exact representation of fractional frame rates like NTSC (30000/1001 ≈ 29.97 fps).

Implementations

impl FrameRate

pub const FILM: Self

24 fps - Film.

pub const FPS_30: Self

30 fps.

pub const FPS_60: Self

60 fps.

pub const NTSC: Self

29.97 fps (30000/1001) - NTSC.

pub const NTSC_FILM: Self

23.976 fps (24000/1001) - Film on NTSC video.

pub const NTSC_HIGH: Self

59.94 fps (60000/1001) - NTSC high frame rate.

pub const PAL: Self

25 fps - PAL.

pub const PAL_HIGH: Self

50 fps - PAL high frame rate.

pub fn new(num: u32, den: u32) -> Option<Self>

Create a new frame rate from numerator and denominator.

Example

use frame_tick::FrameRate;

// 29.97 fps (NTSC)
let ntsc = FrameRate::new(30000, 1001).unwrap();

pub fn from_int(fps: u32) -> Option<Self>

Create an integer frame rate (e.g., 24 fps = 24/1).

pub fn num(&self) -> u32

Get the numerator.

pub fn den(&self) -> u32

Get the denominator.

Trait Implementations

impl Archive for FrameRate

where NonZeroU32: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedFrameRate

The archived representation of this type.

type Resolver = FrameRateResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for FrameRate

fn clone(&self) -> FrameRate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameRate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FrameRate

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<FrameRate, __D> for Archived<FrameRate>

where NonZeroU32: Archive, <NonZeroU32 as Archive>::Archived: Deserialize<NonZeroU32, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<FrameRate, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<'ʄ> Facet<'ʄ> for FrameRate

const SHAPE: &'static Shape

The shape of this type, including: whether it’s a Struct, an Enum, something else?

impl From<NonZero<u32>> for FrameRate

fn from(fps: NonZeroU32) -> Self

Converts to this type from the input type.

impl Hash for FrameRate

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FrameRate

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<__S: Fallible + ?Sized> Serialize<__S> for FrameRate

where NonZeroU32: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for FrameRate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for FrameRate

impl Eq for FrameRate

impl StructuralPartialEq for FrameRate
