Crate feruca

This crate provides a basic implementation of the Unicode Collation Algorithm. There is really just one function, collate, and a few options that can be passed to it. But the implementation conforms to the standard and allows for the use of the CLDR root collation order; so it may indeed be useful, even in this early stage of development.

Structs

CollationOptions

This struct specifies the options to be passed to the collate function. You can choose between two tables (DUCET and CLDR root), and between two approaches to the handling of variable-weight characters (“non-ignorable” and “shifted”). The default, and a good starting point for Unicode collation, is to use the CLDR table with the “shifted” approach.

Enums

KeysSource

This enum provides for a choice of which table of character weights to use.

Functions

collate

This is, so far, the only public function in the library. It accepts as arguments two string references and a CollationOptions struct. It returns an Ordering value. This is designed to be used in conjunction with the sort_by function in the standard library. Simple usage might look like the following…
