BodyWriter

Struct BodyWriter

pub struct BodyWriter<'a>(/* private fields */);

Expand description

Writer for constructing the HTTP response body. Used in body_with.

§Examples

With WriteBuffer:

use maker_web::StatusCode;

resp.status(StatusCode::Ok)
    .body_with(|w| {
        w.write("This goes in the response body");
        w.write("<html>...</html>");
        w.write(true);
    })

With std::io::Write:

use maker_web::StatusCode;
use std::io::Write;

resp.status(StatusCode::Ok)
    .body_with(|w| {
        write!(w, "This goes in the response body");
        write!(w, "{} - {} = {}", 6, 2, 4);
    })

Implementations§

impl BodyWriter<'_>

pub fn write<T: WriteBuffer>(&mut self, value: T)

Appends content to the response body.

Adds data to the body section of the HTTP response. This method only affects the response body, not headers or status.

§Examples

use maker_web::StatusCode;

resp.status(StatusCode::Ok)
    .body_with(|w| {
        w.write("Hello");
        w.write(123);
        w.write(true);
    })
