collate

Rust collation utilities

Example usage:

use collate::*;

let collator = Collator::default();
let collection = [
    [1, 2, 3],
    [2, 3, 4],
    [3, 4, 5],
];

assert_eq!(collator.bisect_left(&collection, &[1]), 0);
assert_eq!(collator.bisect_right(&collection, &[1]), 1);

lib.rs:

Defines a [Collate] trait to standardize collation methods across data types. The provided [Collator] struct can be used to collate a collection of slices of type T where T: Ord. Also provides bisect (with a [Range]), bisect_left, and bisect_right methods.

[Collate] is useful for implementing a B-Tree, or to handle cases where a collator type is more efficient than calling Ord::cmp repeatedly, for example when collating localized strings using rust_icu_ucol. It's also useful to collate types like f32 and f64 which do not support Ord. A [FloatCollator] is provided for this purpose.

Enable the "complex" feature to provide support for collating Complex numbers provided by the num_complex crate.

Example:

# use collate::*;
let collator = Collator::default();
let collection = [
    [1, 2, 3],
    [2, 3, 4],
    [3, 4, 5],
];

assert_eq!(collator.bisect_left(&collection, &[1]), 0);
assert_eq!(collator.bisect_right(&collection, &[1]), 1);
