pub fn format(
secs_since_epoch: u64,
buffer: &mut [u8; 29],
) -> Result<(), TooFuturistic>Expand description
Format a unix timestamp to be used in an HTTP header field into the provided buffer.
Dates are formatted as IMF-fixdate: Fri, 15 May 2015 15:34:21 GMT.
This is a fixed-width format, so this function will always overwrite the entire buffer.
Since this is a fixed-width format, it does not support dates greater than year 9999.
let mut header = [0u8; 29];
assert_eq!(Ok(()), date_header::format(1431704061, &mut header));
assert_eq!(&header, b"Fri, 15 May 2015 15:34:21 GMT");
