Function parse_range 

Source 
pub fn parse_range<'a>(
    value: &'a [u8],
    limits: &Limits,
) -> Result<MediaRange<'a>, ParseError>
Expand description

Parses a media range, as in one member of Accept: */*, type/*, or a media type, with an optional weight.

The first parameter named q (ASCII case-insensitive) is the weight; it and every parameter after it are accept-ext and take no part in matching (RFC 9110 section 12.5.1). A range without q has weight 1.

§Errors

ErrorKind::Wildcard for */subtype; ErrorKind::InvalidQValue; the errors of parse.

§Examples

use parse_net::{media, Limits};

let r = media::parse_range(b"text/*;q=0.5", &Limits::DEFAULT)?;
assert_eq!((r.specificity(), r.weight().thousandths()), (2, 500));
let html = parse_net::parse_media_type(b"text/html")?;
assert!(r.matches(&html));
assert!(media::parse_range(b"*/html", &Limits::DEFAULT).is_err());
