Struct WeightedList 

pub struct WeightedList<'a> { /* private fields */ }

The members of a validated weighted list.

Examples

use parse_net::{negotiate::parse_weighted, Limits};

let w = parse_weighted(b"utf-8, iso-8859-1;q=0.5", &Limits::DEFAULT)?;
assert_eq!(w.len(), 2);
assert!(w.iter().all(|m| m.weight.thousandths() >= 500));

Implementations

impl<'a> WeightedList<'a>

pub fn iter(&self) -> impl Iterator<Item = Weighted<'a>> + '_

The members, in order.

Examples

use parse_net::{negotiate::parse_weighted, Limits};

let w = parse_weighted(b"gzip;q=0.5, br", &Limits::DEFAULT)?;
let best = w.iter().max_by_key(|m| m.weight).map(|m| m.value);
assert_eq!(best, Some(&b"br"[..]));

pub const fn len(&self) -> usize

The number of members.

Examples

use parse_net::{negotiate::parse_weighted, Limits};

assert_eq!(parse_weighted(b"gzip, deflate, br", &Limits::DEFAULT)?.len(), 3);

pub const fn is_empty(&self) -> bool

Whether there are no members.

Examples

use parse_net::{negotiate::parse_weighted, Limits};

assert!(!parse_weighted(b"identity", &Limits::DEFAULT)?.is_empty());
