Struct rocket::http::Header

pub struct Header<'h> {
    pub name: UncasedAscii<'h>,
    pub value: Cow<'h, str>,
}

Simple representation of an HTTP header.

Fields

name: UncasedAscii<'h>

The name of the header.

value: Cow<'h, str>

The value of the header.

Methods

impl<'h> Header<'h>

fn new<'a: 'h, 'b: 'h, N, V>(name: N, value: V) -> Header<'h> where N: Into<Cow<'a, str>>, V: Into<Cow<'b, str>>

Constructs a new header. This method should be used rarely and only for non-standard headers. Instead, prefer to use the Into<Header> implementations of many types, including ContentType and all of the headers in http::hyper::header.

Examples

Create a custom header with name X-Custom-Header and value custom value.

use rocket::http::Header;

let header = Header::new("X-Custom-Header", "custom value");
assert_eq!(header.to_string(), "X-Custom-Header: custom value");

Use a String as a value to do the same.

use rocket::http::Header;

let value = format!("{} value", "custom");
let header = Header::new("X-Custom-Header", value);
assert_eq!(header.to_string(), "X-Custom-Header: custom value");

fn name(&self) -> &str

Returns the name of this header with casing preserved. To do a case-insensitive equality check, use .name directly.

Example

A case-sensitive equality check:

use rocket::http::Header;

let value = format!("{} value", "custom");
let header = Header::new("X-Custom-Header", value);
assert_eq!(header.name(), "X-Custom-Header");
assert!(header.name() != "X-CUSTOM-HEADER");

A case-insensitive equality check via .name:

use rocket::http::Header;

let header = Header::new("X-Custom-Header", "custom value");
assert_eq!(header.name, "X-Custom-Header");
assert_eq!(header.name, "X-CUSTOM-HEADER");

fn value(&self) -> &str

Returns the value of this header.

Example

A case-sensitive equality check:

use rocket::http::Header;

let header = Header::new("X-Custom-Header", "custom value");
assert_eq!(header.value(), "custom value");
