HTTP accept header
A very basic & naive implementation of the HTTP Accept header. It uses http crate and mime crate to parse the accept header. Basic data structure:
#[derive(Debug, Clone, PartialEq)]
pub struct Accept {
pub wildcard: Option<MediaType>,
pub types: Vec<MediaType>,
}
#[derive(Debug, Clone, PartialEq)]
pub struct MediaType {
pub mime: Mime,
pub weight: Option<f32>,
}
Usage:
// parse accept header
let accept: Accept = "application/json, text/html;q=0.9, text/plain;q=0.8, */*;q=0.7"
.parse()
.unwrap();
// prepare a list of supported media types
let available = vec![
Mime::from_str("text/html").unwrap(),
Mime::from_str("application/json").unwrap(),
];
// content negotiation
let negotiated = accept.negotiate(&available).unwrap();
// "application/json" shall be chosen since it is available and has the highest weight
assert_eq!(negotiated, Mime::from_str("application/json").unwrap());
