Struct trillium_http::HeaderValues

pub struct HeaderValues(_);

A header value is a collection of one or more HeaderValue. It has been optimized for the “one HeaderValue” case, but can accomodate more than one value.

Implementations

impl HeaderValues

pub fn new() -> Self

Builds an empty HeaderValues. This is not generally necessary in application code. Using a From implementation is preferable.

pub fn as_str(&self) -> Option<&str>

If there is only a single value, returns that header as a borrowed string slice if it is utf8. If there are more than one header value, or if the singular header value is not utf8, as_str returns None.

pub fn one(&self) -> Option<&HeaderValue>

If there is only a single HeaderValue inside this HeaderValues, one returns a reference to that value. If there are more than one header value inside this headervalues, one returns None.

pub fn append(&mut self, value: impl Into<HeaderValue>)

Add another header value to this HeaderValues.

pub fn extend(&mut self, values: impl Into<HeaderValues>)

Adds any number of other header values to this header values.

Trait Implementations

impl Clone for HeaderValues

fn clone(&self) -> HeaderValues

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HeaderValues

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

Formats the value using the given formatter.

impl Default for HeaderValues

fn default() -> Self

Returns the “default value” for a type.

type Target = [HeaderValue]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for HeaderValues

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl From<&'static str> for HeaderValues

fn from(s: &'static str) -> Self

Performs the conversion.

impl From<HeaderValue> for HeaderValues

fn from(v: HeaderValue) -> Self

Performs the conversion.

impl From<String> for HeaderValues

impl IntoIterator for HeaderValues

type Item = HeaderValue

The type of the elements being iterated over.

type IntoIter = IntoIter<[HeaderValue; 1]>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter
