Struct Fraction

pub struct Fraction {
    pub numerator: u32,
    pub denominator: u32,
}

Fraction representation used for timing settings.

This is only a representation of the data returned by the backend, not a mathematical type. Two Fractions are equal when fields are equal, not when they are the equal rational number.

Fields

numerator: u32

denominator: u32

Implementations

impl Fraction

pub fn new(num: u32, denom: u32) -> Self

Returns a fraction representation

Arguments

• num - Numerator
• denom - Denominator

Example

use v4l::fraction::Fraction;
let frac = Fraction::new(30, 1);

Trait Implementations

impl Clone for Fraction

fn clone(&self) -> Fraction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Fraction

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

Formats the value using the given formatter.

impl Default for Fraction

fn default() -> Fraction

Returns the “default value” for a type.

impl Display for Fraction

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

Formats the value using the given formatter.

impl From<Fraction> for v4l2_fract

fn from(fraction: Fraction) -> Self

Converts to this type from the input type.

impl From<v4l2_fract> for Fraction

fn from(frac: v4l2_fract) -> Self

Converts to this type from the input type.

impl Hash for Fraction

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 Fraction

fn eq(&self, other: &Fraction) -> 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.
