Struct hyper::header::Formatter
[−]
[src]
pub struct Formatter<'a, 'b: 'a>(_);
A formatter used to serialize headers to an output stream.
Methods
impl<'a, 'b> Formatter<'a, 'b>
[src]
fn fmt_line(&mut self, line: &Display) -> Result
[src]
Format one 'line' of a header.
This writes the header name plus the Display
value as a single line.
Note
This has the ability to format a header over multiple lines.
The main example here is Set-Cookie
, which requires that every
cookie being set be specified in a separate line. Almost every other
case should only format as 1 single line.
