Struct generic_async_http_client::HeaderValue

source · [−]

#[repr(transparent)]
pub struct HeaderValue(_);

Expand description

A HTTP Header Value

It can be converted from &[u8] and &str. You can obtain a &[u8] reference and compare with str and &[u8]. You can also convert it to String if it is valid utf-8.

use std::convert::TryInto;
use generic_async_http_client::HeaderValue;
let hv: HeaderValue = b"test"[..].try_into().unwrap();
assert!(hv=="test");
assert!(hv.as_ref().contains(&b's'));
let val: String = hv.try_into().unwrap();
