Struct rocket::local::blocking::LocalResponse[][src]

pub struct LocalResponse<'c> { /* fields omitted */ }
Expand description

A blocking response from a dispatched LocalRequest.

This LocalResponse implements io::Read. As such, if into_string() and into_bytes() do not suffice, the response’s body can be read directly:

use std::io::{self, Read};

use rocket::local::blocking::Client;
use rocket::http::Status;

#[get("/")]
fn hello_world() -> &'static str {
    "Hello, world!"
}

#[launch]
fn rocket() -> _ {
    rocket::build().mount("/", routes![hello_world])
}

// Dispatch a `GET /` request.
let client = Client::tracked(rocket()).expect("valid rocket");
let mut response = client.get("/").dispatch();

// Check metadata validity.
assert_eq!(response.status(), Status::Ok);
assert_eq!(response.body().preset_size(), Some(13));

// Read 10 bytes of the body. Note: in reality, we'd use `into_string()`.
let mut buffer = [0; 10];
response.read(&mut buffer)?;
assert_eq!(buffer, "Hello, wor".as_bytes());

Implementations

Returns the HTTP status of self.

Example

use rocket::local::blocking::LocalResponse;

let response: LocalResponse = response;
let status = response.status();

Returns the Content-Type, if a valid one is set, of self.

Example

use rocket::local::blocking::LocalResponse;

let response: LocalResponse = response;
let content_type = response.content_type();

Returns the HTTP headers of self.

Example

use rocket::local::blocking::LocalResponse;

let response: LocalResponse = response;
let headers = response.headers();

Return a cookie jar containing the HTTP cookies in the response.

Example

use rocket::local::blocking::LocalResponse;

let response: LocalResponse = response;
let string = response.cookies();

Returns the response body, if there is one, of self.

Example

use rocket::local::blocking::LocalResponse;

let response: LocalResponse = response;
let body = response.body();

Consumes self and reads the entirety of its body into a string.

If reading fails, the body contains invalid UTF-8 characters, or the body is unset in the response, returns None. Otherwise, returns Some. The string may be empty if the body is empty.

Example

use rocket::local::blocking::LocalResponse;

let response: LocalResponse = response;
let string = response.into_string();

Consumes self and reads the entirety of its body into a Vec of bytes.

If reading fails or the body is unset in the response, returns None. Otherwise, returns Some. The returned vector may be empty if the body is empty.

Example

use rocket::local::blocking::LocalResponse;

let response: LocalResponse = response;
let bytes = response.into_bytes();
This is supported on crate feature json only.

Consumes self and deserializes its body as JSON without buffering in memory.

If deserialization fails or the body is unset in the response, returns None. Otherwise, returns Some.

Example

use rocket::local::blocking::LocalResponse;
use rocket::serde::Deserialize;

#[derive(Deserialize)]
struct Task {
    id: usize,
    complete: bool,
    text: String,
}

let response: LocalResponse = response;
let task = response.into_json::<Task>();
This is supported on crate feature msgpack only.

Consumes self and deserializes its body as MessagePack without buffering in memory.

If deserialization fails or the body is unset in the response, returns None. Otherwise, returns Some.

Example

use rocket::local::blocking::LocalResponse;
use rocket::serde::Deserialize;

#[derive(Deserialize)]
struct Task {
    id: usize,
    complete: bool,
    text: String,
}

let response: LocalResponse = response;
let task = response.into_msgpack::<Task>();
