Struct Response 

pub struct Response { /* private fields */ }

One response, written whole or streamed.

Implementations

impl Response

pub fn new(status: u16, content_type: &'static str, body: Vec<u8>) -> Self

body with status and its content type.

pub fn stream( content_type: &'static str, body: impl FnOnce(&mut dyn Write) -> Result<()> + Send + 'static, ) -> Self

A 200 whose body body writes after the head, as it is made, until it returns; the connection’s close then ends it. It is never cached.

pub const fn cached(self, policy: &'static str) -> Self

The same response kept by caches as policy says, in place of no-store.

pub fn json(status: u16, value: &Value) -> Self

A JSON answer.

pub fn no_content() -> Self

A 204: no body, so no Content-Type and no Content-Length.

pub fn redirect(location: &str) -> Self

Send the browser to location.

pub fn with(self, name: &'static str, value: &str) -> Self

The same response with one more header.

pub fn write(self, output: &mut impl Write) -> Result<()>

Write the response to output; a streamed body is written until it ends.

Errors

InvalidData, before anything is written, for a header value holding a line break; otherwise the write’s own error, or the stream’s.

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