Struct Formatter

pub struct Formatter<'a, 'b: 'a>(/* private fields */);

A formatter used to serialize headers to an output stream.

Implementations

impl<'a, 'b> Formatter<'a, 'b>

pub fn fmt_line(&mut self, line: &dyn Display) -> Result

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.
