Struct headers_core::ToValues

pub struct ToValues<'a> { /* fields omitted */ }

A builder to append HeaderValues to during Header::encode.

Methods

impl<'a> ToValues<'a>

pub fn append(&mut self, value: HeaderValue)

Append the HeaderValue to the existing list of headers.

While this can be called multiple times, most headers should only call this once. The exceptions are outliers like Set-Cookie.

pub fn append_fmt<T: Display>(&mut self, fmt: T)

Append the impl Display to the list of headers.

Panics

Encoding HeaderValues is expected to be infallible. However, not all UTF-8 sequences are valid for a HeaderValue. The type passed here must ensure that its resulting string is a valid HeaderValue.

Trait Implementations

impl<'a> Debug for ToValues<'a>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
