Struct rouille::ResponseBody

pub struct ResponseBody { /* fields omitted */ }

An opaque type that represents the body of a response.

You can't access the inside of this struct, but you can build one by using one of the provided constructors.

Example

use rouille::ResponseBody;
let body = ResponseBody::from_string("hello world");

Methods

impl ResponseBody

pub fn empty() -> ResponseBody

Builds a ResponseBody that doesn't return any data.

Example

use rouille::ResponseBody;
let body = ResponseBody::empty();

pub fn from_reader<R>(data: R) -> ResponseBody where
    R: Read + Send + 'static, 

Builds a new ResponseBody that will read the data from a Read.

Note that this is suboptimal compared to other constructors because the length isn't known in advance.

Example

use std::io;
use std::io::Read;
use rouille::ResponseBody;

let body = ResponseBody::from_reader(io::stdin().take(128));

pub fn from_data<D>(data: D) -> ResponseBody where
    D: Into<Vec<u8>>, 

Builds a new ResponseBody that returns the given data.

Example

use rouille::ResponseBody;
let body = ResponseBody::from_data(vec![12u8, 97, 34]);

pub fn from_file(file: File) -> ResponseBody

Builds a new ResponseBody that returns the content of the given file.

Example

use std::fs::File;
use rouille::ResponseBody;

let file = File::open("page.html").unwrap();
let body = ResponseBody::from_file(file);

pub fn from_string<S>(data: S) -> ResponseBody where
    S: Into<String>, 

Builds a new ResponseBody that returns an UTF-8 string.

Example

use rouille::ResponseBody;
let body = ResponseBody::from_string("hello world");

pub fn into_reader_and_size(self) -> (Box<dyn Read + Send>, Option<usize>)

Extracts the content of the response.

Returns the size of the body and the body itself. If the size is None, then it is unknown.
