Struct TagSet 

pub struct TagSet { /* private fields */ }

A compact set of file tags represented as a fixed-size bitset.

Each bit corresponds to an index in tags::ALL_TAGS. This keeps membership / set operations fast and allocation-free.

Implementations

impl TagSet

pub const fn new(tag_ids: &[u16]) -> Self

Constructs a TagSet from tag ids.

tag_ids must reference valid indexes in [tags::ALL_TAGS_BY_ID]. Duplicate ids are allowed and are automatically coalesced.

pub fn from_tags<I, S>(tags: I) -> Self

where I: IntoIterator<Item = S>, S: AsRef<str>,

Constructs a TagSet from tag strings.

Unknown tags are ignored in release builds and debug-asserted in debug builds.

pub const fn insert(&mut self, tag_id: u16)

pub fn is_disjoint(&self, other: &TagSet) -> bool

Returns true if the two sets do not share any tag.

pub fn is_subset(&self, other: &TagSet) -> bool

Returns true if all tags in self are also present in other.

pub fn iter(&self) -> TagSetIter<'_>

Iterates tags in deterministic id order.

pub fn is_empty(&self) -> bool

Returns true if the set contains no tags.
