Implementations

impl Headers

pub fn new() -> Headers

Construct empty headers

pub fn from_vec(headers: Vec<Header>) -> Headers

pub fn iter(&self) -> impl Iterator<Item = &Header>

Return an iterator over headers.

Pseudo headers returned first.

pub fn dump(&self) -> String

Dump all headers as multiline string.

pub fn new_get(path: impl Into<HeaderValue>) -> Headers

Construct a Headers object with specified :method and :path headers

pub fn new_post(path: impl Into<HeaderValue>) -> Headers

Construct a Headers object with specified :method and :path headers

Construct a Headers object with single :status header

pub fn ok_200() -> Headers

Construct :status 200 headers

pub fn not_found_404() -> Headers

Construct :status 404 headers

pub fn internal_error_500() -> Headers

Construct :status 500 headers

pub fn redirect_302(location: impl Into<HeaderValue>) -> Headers

Construct :status 302; location: <location> headers

pub fn get_opt<'a>(&'a self, name: &str) -> Option<&'a str>

Lookup header.

pub fn get<'a>(&'a self, name: &str) -> &'a str

Lookup header.

Panics

If header is not found.

pub fn get_opt_parse<I: FromStr>(&self, name: &str) -> Option<I>

Lookup header.

pub fn status(&self) -> u32

Status header value.

pub fn path(&self) -> &str

Path header.

pub fn method(&self) -> &str

Method header.

pub fn content_length(&self) -> Option<u64>

Content-length header.

pub fn add( &mut self, name: impl Into<HeaderName>, value: impl Into<HeaderValue>, )

Add a header

pub fn add_header(&mut self, header: Header)

Add a header

pub fn extend(&mut self, headers: Headers)

Add all headers

Trait Implementations

impl Clone for Headers

fn clone(&self) -> Headers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Headers

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

Formats the value using the given formatter.

impl Default for Headers

fn default() -> Headers

Returns the “default value” for a type.

impl FromIterator<Header> for Headers

fn from_iter<T: IntoIterator<Item = Header>>(iter: T) -> Headers

Creates a value from an iterator.

impl PartialEq for Headers

fn eq(&self, other: &Headers) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
