Crate abjad

This library is meant to facilitate calculating the numerical abjad value of a string of text in Arabic or Persian (support for other Arabic-script languages may be added over time).

At the moment, this simply adds three methods for &str:

• abjad returns a best-effort value, ignoring unrecognized characters.
• abjad_collect_errors also records unrecognized characters in a Vec.
• abjad_strict returns an error as soon as any character is not recognized.

Structs

AbjadPrefs

We need to allow some options for abjad calculation. At present there are four. All are false by default. If you don’t need to activate any of them, when calling one of the methods, you can pass AbjadPrefs::default().

Enums

AbjadError

The error type for this crate. Currently there is only one member: UnrecognizedCharacter, which is returned by abjad_strict upon encountering any character outside of the Arabic script.

Traits

Abjad

This is the trait that we implement for &str, allowing us to use the new methods.
