Struct Quality

pub struct Quality(/* private fields */);

A quality value, as specified in RFC7231.

Quality values are decimal numbers between 0 and 1 (inclusive) with up to 3 fractional digits of precision.

Implementations

impl Quality

pub fn from_u16(quality: u16) -> Quality

Creates a quality value from a value between 0 and 1000 inclusive.

This is semantically divided by 1000 to produce a value between 0 and 1.

Panics

Panics if the value is greater than 1000.

pub fn as_u16(&self) -> u16

Returns the quality multiplied by 1000 as an integer.

Trait Implementations

impl Clone for Quality

fn clone(&self) -> Quality

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Quality

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

Formats the value using the given formatter.

impl Ord for Quality

fn cmp(&self, other: &Quality) -> 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.

impl PartialEq for Quality

fn eq(&self, other: &Quality) -> 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 PartialOrd for Quality

fn partial_cmp(&self, other: &Quality) -> 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.
