Struct ResponseHeader 

pub struct ResponseHeader { /* private fields */ }

The HTTP response header type.

This type is similar to http::response::Parts but preserves header name case. ResponseHeader implements Deref for http::response::Parts so it can be used as it in most places.

Implementations

impl ResponseHeader

pub fn build( code: impl TryInto<StatusCode>, size_hint: Option<usize>, ) -> Result<ResponseHeader, Box<Error>>

Create a new ResponseHeader with the given status code.

pub fn build_no_case( code: impl TryInto<StatusCode>, size_hint: Option<usize>, ) -> Result<ResponseHeader, Box<Error>>

Create a new ResponseHeader with the given status code without preserving header case.

A ResponseHeader created from this type is more space efficient than those from Self::build().

Use this method if reading from or writing to HTTP/2 sessions where header case doesn’t matter anyway.

pub fn append_header( &mut self, name: impl IntoCaseHeaderName, value: impl TryInto<HeaderValue>, ) -> Result<bool, Box<Error>>

Append the header name and value to self.

If there are already some headers under the same name, a new value will be added without any others being removed.

pub fn insert_header( &mut self, name: impl IntoCaseHeaderName, value: impl TryInto<HeaderValue>, ) -> Result<(), Box<Error>>

Insert the header name and value to self.

Different from Self::append_header(), this method will replace all other existing headers under the same name (case insensitive).

pub fn remove_header<'a, N>(&mut self, name: &'a N) -> Option<HeaderValue>

where &'a N: 'a + AsHeaderName, N: ?Sized,

Remove all headers under the name

pub fn header_to_h1_wire(&self, buf: &mut impl BufMut)

Write the header to the buf in HTTP/1.1 wire format.

The header case will be preserved.

pub fn set_status( &mut self, status: impl TryInto<StatusCode>, ) -> Result<(), Box<Error>>

Set the status code

pub fn set_version(&mut self, version: Version)

Set the HTTP version

pub fn set_reason_phrase( &mut self, reason_phrase: Option<&str>, ) -> Result<(), Box<Error>>

Set the HTTP reason phase. If None, a default reason phase will be used

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

Get the HTTP reason phase. If Self::set_reason_phrase() is never called or set to None, a default reason phase will be used

pub fn as_owned_parts(&self) -> Parts

Clone self into http::response::Parts.

pub fn set_content_length(&mut self, len: usize) -> Result<(), Box<Error>>

Helper function to set the HTTP content length on the response header.

Trait Implementations

impl AsRef<Parts> for ResponseHeader

fn as_ref(&self) -> &Parts

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ResponseHeader

fn clone(&self) -> ResponseHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResponseHeader

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

Formats the value using the given formatter.

impl Deref for ResponseHeader

type Target = Parts

The resulting type after dereferencing.

fn deref(&self) -> &<ResponseHeader as Deref>::Target

Dereferences the value.

impl From<Parts> for ResponseHeader

fn from(parts: Parts) -> ResponseHeader

Converts to this type from the input type.

impl From<ResponseHeader> for Parts

fn from(resp: ResponseHeader) -> Parts

Converts to this type from the input type.
