Struct QualityValue 

pub struct QualityValue<T> {
    pub value: T,
    pub quality: Quality,
}

Represents an item with a quality value as defined in RFC7231.

Fields

value: T

The actual contents of the field.

quality: Quality

The quality (client or server preference) for the value.

Implementations

impl<T> QualityValue<T>

pub const fn new(value: T, quality: Quality) -> QualityValue<T>

Creates a new QualityValue from an item and a quality.

pub const fn new_value(value: T) -> QualityValue<T>

Creates a new QualityValue from an item value alone.

Trait Implementations

impl<T> Clone for QualityValue<T>

where T: Clone,

fn clone(&self) -> QualityValue<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Copy for QualityValue<T>

where T: Copy,

impl<T> Debug for QualityValue<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Display for QualityValue<T>

where T: Display,

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

Formats the value using the given formatter.

impl<T> Eq for QualityValue<T>

where T: Eq,

impl<T> From<T> for QualityValue<T>

fn from(value: T) -> QualityValue<T>

Converts to this type from the input type.

impl<T> FromStr for QualityValue<T>

where T: FromStr,

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<QualityValue<T>, Error>

Parses a string s to return a value of this type.

impl<T> PartialEq for QualityValue<T>

where T: PartialEq,

fn eq(&self, other: &QualityValue<T>) -> 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<T> PartialOrd for QualityValue<T>

where T: PartialEq,

fn partial_cmp(&self, other: &QualityValue<T>) -> 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.
