UNIC — Unicode Character Tools — Character Range

A simple way to control iteration over a range of characters.

Examples

#[macro_use] extern crate unic_char_range;

# fn main() {
for character in chars!('a'..='z') {
// character is each character in the lowercase english alphabet in order
}

for character in chars!(..) {
// character is every valid char from lowest codepoint to highest
}
# }

Features

None of these features are included by default; they rely on unstable Rust feature gates.

• unstable: enables all features
• exact-size-is-empty: provide a specific impl of ExactSizeIterator::is_empty
• trusted-len: impl the TrustedLen contract
