Struct ResponseHead 

pub struct ResponseHead {
    pub version: Version,
    pub status: StatusCode,
    pub headers: HeaderMap,
    pub headers_vec: Vec<HeaderItem>,
    pub reason: Option<&'static str>,
    /* private fields */
}

The metadata for an HTTP response.

Fields

version: Version

HTTP protocol version.

status: StatusCode

Response status code.

headers: HeaderMap

Response headers.

headers_vec: Vec<HeaderItem>

Headers in their original order and with their original names.

This collection is populated when decoding a response with HttpServiceConfig::set_headers_vec enabled.

reason: Option<&'static str>

Custom reason phrase, or None to use the status code’s standard phrase.

Implementations

impl ResponseHead

pub fn new(status: StatusCode, version: Version) -> ResponseHead

Creates response metadata with the supplied status and HTTP version.

pub fn extensions(&self) -> Ref<'_, Extensions>

Returns the response extensions.

pub fn extensions_mut(&self) -> RefMut<'_, Extensions>

Returns mutable access to the response extensions.

pub fn headers(&self) -> &HeaderMap

Returns the response headers.

pub fn headers_mut(&mut self) -> &mut HeaderMap

Returns mutable access to the response headers.

pub fn headers_vec(&self) -> &[HeaderItem]

Returns headers preserved in their original order and casing.

pub fn set_connection_type(&mut self, ctype: ConnectionType)

Sets the response connection behavior.

Connection types are flags, and calling this method again does not clear a previously set type. When several are set, Close takes precedence over KeepAlive, which takes precedence over Upgrade.

pub fn connection_type(&self) -> ConnectionType

Returns the response’s connection behavior.

pub fn keep_alive(&self) -> bool

Returns whether the response keeps the connection open.

pub fn upgrade(&self) -> bool

Returns whether the response upgrades the connection.

pub fn reason(&self) -> &str

Returns the custom or canonical reason phrase.

The reason phrase is empty for a status code without a canonical reason.

pub fn chunked(&self) -> bool

Returns whether HTTP/1 chunked transfer encoding is allowed.

pub fn no_chunking(&mut self, val: bool)

Enables or disables HTTP/1 chunked transfer encoding.

Trait Implementations

impl Debug for ResponseHead

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

Formats the value using the given formatter.

impl Default for ResponseHead

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<&'a ResponseHead> for ResponseBuilder

Convert ResponseHead to a ResponseBuilder

fn from(head: &'a ResponseHead) -> ResponseBuilder

Converts to this type from the input type.
