Struct Rate 

pub struct Rate { /* private fields */ }

An exact positive video frame rate, in frames per second.

Implementations

impl Rate

pub fn new(numerator: u32, denominator: u32) -> Result<Self, RateError>

Construct an exact rate from a numerator and denominator.

pub fn from_f64(value: f64) -> Result<Self, RateError>

Approximate a finite catalog rate using 32-bit rational components.

pub fn numerator(self) -> u32

The frames-per-second numerator.

pub fn denominator(self) -> u32

The frames-per-second denominator.

pub fn as_f64(self) -> f64

Convert the exact rate to a floating-point catalog value.

pub fn rounded(self) -> u32

Round to the nearest whole frame rate for integer-only platform APIs.

pub fn frames(self, duration: Duration) -> u32

Number of frames in duration, rounded to the nearest frame.

Trait Implementations

impl Eq for Rate

impl Hash for Rate

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,

impl Ord for Rate

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Rate

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Rate

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
