Struct jsonrpc_client_http::header::Quality

pub struct Quality(_);

Represents a quality used in quality values.

Can be created with the q function.

Implementation notes

The quality value is defined as a number between 0 and 1 with three decimal places. This means there are 1001 possible values. Since floating point numbers are not exact and the smallest floating point data type (f32) consumes four bytes, hyper uses an u16 value to store the quality internally. For performance reasons you may set quality directly to a value between 0 and 1000 e.g. Quality(532) matches the quality q=0.532.

RFC7231 Section 5.3.1 gives more information on quality values in HTTP header fields.

Trait Implementations

impl PartialOrd<Quality> 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: &Quality) -> bool

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

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<(), Error>

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl Default for Quality

fn default() -> Quality

Returns the "default value" for a type.

impl Copy for Quality

impl Eq for Quality

impl PartialEq<Quality> for Quality

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
