pub fn parse_i64(s: &[u8]) -> Option<i64>Expand description
Parses a signed decimal integer the way Redis’s string2ll does.
Returns None for anything it would reject, which includes an empty slice,
a leading +, a leading zero on a non zero number, any non digit anywhere,
and anything that does not fit in an i64. The protocol’s array and bulk
lengths are parsed with this, so being looser here would mean accepting
frames that Redis rejects, and being stricter would mean the reverse.
