impl Response

source

pub fn from_head(head: &[u8]) -> Result<Response, Error>

Creates new Response with head - status and headers - parsed from a slice of bytes

Examples
use http_req::response::Response;

const HEAD: &[u8; 102] = b"HTTP/1.1 200 OK\r\n\
                         Date: Sat, 11 Jan 2003 02:44:04 GMT\r\n\
                         Content-Type: text/html\r\n\
                         Content-Length: 100\r\n\r\n";

let response = Response::from_head(HEAD).unwrap();
source

pub fn try_from<T: Write>(res: &[u8], writer: &mut T) -> Result<Response, Error>

Parses Response from slice of bytes. Writes it’s body to writer.

Examples
use http_req::response::Response;

const RESPONSE: &[u8; 129] = b"HTTP/1.1 200 OK\r\n\
                             Date: Sat, 11 Jan 2003 02:44:04 GMT\r\n\
                             Content-Type: text/html\r\n\
                             Content-Length: 100\r\n\r\n\
                             <html>hello\r\n\r\nhello</html>";
let mut body = Vec::new();

let response = Response::try_from(RESPONSE, &mut body).unwrap();
source

pub const fn status_code(&self) -> StatusCode

Returns status code of this Response.

Examples
use http_req::response::{Response, StatusCode};

const RESPONSE: &[u8; 129] = b"HTTP/1.1 200 OK\r\n\
                             Date: Sat, 11 Jan 2003 02:44:04 GMT\r\n\
                             Content-Type: text/html\r\n\
                             Content-Length: 100\r\n\r\n\
                             <html>hello\r\n\r\nhello</html>";
let mut body = Vec::new();

let response = Response::try_from(RESPONSE, &mut body).unwrap();
assert_eq!(response.status_code(), StatusCode::new(200));
