Hi,
There are lots of protocols based on ASCII character representation. In
Rust, the natural way to represent them is
by an u8 literal (optionally wrapped within std::ascii::Ascii).
What I am missing is a simple way to represent those literals in code.
What I am doing most of the time is:
fn read_char() -> Option<char> {
match io.read_byte() {
Some(b) => Some(b as char),
None => None
}
}
And then use character literals in pattern matching. What I'd highly
prefer is a way to directly repesent ASCII characters
in the code, like:
match io.read_byte().unwrap {
'c'_ascii => ....
....
}
If macros would work in patterns, something like:
match ... {
ascii!('a') => ...
}
would work for me too. Ideally that would work with range patterns as
well, but of course an ascii_range!() macro would
do the same.
Is this useful to anyone?
Regards,
Michael
