pub fn parse_if_range(value: &[u8]) -> Result<IfRange<'_>, ParseError>Expand description
Parses If-Range without a clock: an entity tag when the value starts
with W/ or ", an IMF-fixdate or asctime date otherwise. An RFC 850
date needs the current time to place its year, so it takes
parse_if_range_at; here it is ErrorKind::InvalidDate.
§Errors
The errors of EntityTag::parse or HttpDate::parse_at.
§Examples
use parse_net::{range::parse_if_range, IfRange};
assert!(matches!(parse_if_range(b"\"abc\"")?, IfRange::Tag(t) if t.opaque() == b"abc"));
assert!(matches!(parse_if_range(b"Sun, 06 Nov 1994 08:49:37 GMT")?, IfRange::Date(_)));
assert!(parse_if_range(b"tomorrow").is_err());
