Struct rocket::http::Header

pub struct Header<'h> {
    pub name: Uncased<'h>,
    pub value: Cow<'h, str>,
}
Expand description

Simple representation of an HTTP header.

Fields§

§name: Uncased<'h>

The name of the header.

§value: Cow<'h, str>

The value of the header.

Implementations§

§

impl<'h> Header<'h>

pub fn new<'a, 'b, N, V>(name: N, value: V) -> Header<'h>
where 'a: 'h, 'b: 'h, 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");

pub fn name(&self) -> &UncasedStr

Returns the name of this header.

§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().as_str(), "X-Custom-Header");
assert_ne!(header.name().as_str(), "X-CUSTOM-HEADER");

A case-insensitive equality check:

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");

pub 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");

source§

fn quirk(&self, value: Quirk) -> Painted<&T>
