ellidri-unicase
A wrapper around str
that makes comparisons case-insensitive.
Used for ellidri.
lib.rs
:
Wrapper around str that makes comparisons case-insensitive.
Intended for use within a HashMap
. Actually used by ellidri's State
. It doesn't support
Unicode case-folding for now.
The wrapper is named UniCase
. It implements traits so that &UniCase<str>
behaves like
&str
, and UniCase<String>
behaves like String
, except for the comparisons of course,
which are case-insensitive.
"Case-insensitivity" is defined by the CaseMapping
trait. This trait defines how characters
and bytes should match. Currently, the following case mappings are available:
Ascii
(default): matches ascii lower case letters with their ascii upper case counterparts,Rfc1459
: same asAscii
, but also matches{}|^
with[]\~
.Rfc1459Strict
: same asAscii
, but also matches{}|
with[]\
.
Currently, rfc7613
is not implemented.
Usage
use ellidri_unicase::{u, UniCase};
use std::collections::HashSet;
let mut channels = HashSet::new();
channels.insert(UniCase::new("#Games".to_owned()));
assert!(channels.contains(u("#gameS")));
assert!(!channels.contains(u("#Gaming")));
assert_eq!(u("hello!"), u("HELLO!"));
