Struct rocket::http::hyper::header::ContentLength

pub struct ContentLength(pub u64);

Content-Length header, defined in RFC7230

When a message does not have a Transfer-Encoding header field, a Content-Length header field can provide the anticipated size, as a decimal number of octets, for a potential payload body. For messages that do include a payload body, the Content-Length field-value provides the framing information necessary for determining where the body (and message) ends. For messages that do not include a payload body, the Content-Length indicates the size of the selected representation.

ABNF

Content-Length = 1*DIGIT

Example

use hyper::header::{Headers, ContentLength};
 
let mut headers = Headers::new();
headers.set(ContentLength(1024u64));

Methods from Deref<Target = u64>

pub const MIN: u64

pub const MAX: u64

pub const BITS: u32

pub fn as_ne_bytes(&self) -> &[u8; 8]

🔬 This is a nightly-only experimental API. (num_as_ne_bytes)

Return the memory representation of this integer as a byte array in native byte order.

to_ne_bytes should be preferred over this whenever possible.

Examples

#![feature(num_as_ne_bytes)]
let num = 0x1234567890123456u64;
let bytes = num.as_ne_bytes();
assert_eq!(
    bytes,
    if cfg!(target_endian = "big") {
        &[0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]
    } else {
        &[0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12]
    }
);
