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 items of type T where T: Ord.

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 handle types like complex numbers which do not necessarily have a natural ordering.

Use the "stream" feature flag to enable diff and try_diff functions to compute the difference between two collated Streams, and the merge and try_merge functions to merge two collated Streams.
