Struct Connection

pub struct Connection(/* private fields */);
Expand description

Connection header, defined in RFC7230

The Connection header field allows the sender to indicate desired control options for the current connection. In order to avoid confusing downstream recipients, a proxy or gateway MUST remove or replace any received connection options before forwarding the message.

§ABNF

Connection        = 1#connection-option
connection-option = token

# Example values
* `close`
* `keep-alive`
* `upgrade`

§Examples

use rama_http_headers::Connection;

let keep_alive = Connection::keep_alive();

Implementations§

§

impl Connection

pub fn close() -> Connection

A constructor to easily create a Connection: close header.

pub fn contains_close(&self) -> bool

Returns true if this Connection header contains close.

pub fn keep_alive() -> Connection

A constructor to easily create a Connection: keep-alive header.

pub fn contains_keep_alive(&self) -> bool

Returns true if this Connection header contains keep-alive.

pub fn upgrade() -> Connection

A constructor to easily create a Connection: Upgrade header.

pub fn contains_upgrade(&self) -> bool

Returns true if this Connection header contains Upgrade.

pub fn contains(&self, name: impl AsConnectionOption) -> bool

Check if this header contains a given “connection option”.

This can be used with various argument types:

  • &str
  • &HeaderName
  • HeaderName
§Example
use rama_http_types::header::UPGRADE;
use rama_http_headers::Connection;

let conn = Connection::keep_alive();

assert!(!conn.contains("close"));
assert!(!conn.contains(UPGRADE));
assert!(conn.contains("keep-alive"));
assert!(conn.contains("Keep-Alive"));
