Struct WritingSystemSet 

pub struct WritingSystemSet(/* private fields */);

A compact set of WritingSystems, backed by a u128 bitset (33 variants ≪ 128 bits). Hand-rolled to avoid a bitflags dependency (the workspace uses none).

Implementations

impl WritingSystemSet

pub const fn new() -> Self

The empty set.

pub fn insert(&mut self, ws: WritingSystem)

Add a writing system.

pub const fn contains(self, ws: WritingSystem) -> bool

True if ws is present.

pub const fn is_empty(self) -> bool

True if no writing system is present.

pub const fn len(self) -> u32

Number of writing systems present.

pub const fn union(self, other: Self) -> Self

The union of two sets.

pub fn iter(self) -> impl Iterator<Item = WritingSystem>

Iterate the present writing systems in WritingSystem::ALL order.
