Struct DomTokenList 

pub struct DomTokenList { /* private fields */ }

Snapshot of an element’s ordered class tokens (DOM Element.classList read-side view). Re-construct via the element accessor to refresh after a class mutation.

tokens preserves the iteration order of the underlying class set; rdom-core stores classes in a BTreeSet, so iteration is alphabetic. Browsers preserve insertion order; this is a documented divergence (the same one class_list() has carried since Phase 1).

Implementations

impl DomTokenList

pub fn from_tokens(tokens: impl IntoIterator<Item = String>) -> Self

Construct from an iterator of class tokens. Used by the NodeRef::class_list() integration (M4b step 14); exposed publicly so tests and other consumers can build snapshots directly.

pub fn len(&self) -> usize

Number of tokens in the snapshot. DOM length.

pub fn is_empty(&self) -> bool

true iff the snapshot has no tokens.

pub fn item(&self, index: usize) -> Option<&str>

Borrow the token at index, or None if out of bounds. DOM item(i).

pub fn value(&self) -> String

Re-serialize the snapshot as a space-joined string. DOM value / toString().

pub fn contains(&self, token: &str) -> bool

true iff the snapshot contains token. DOM contains.

pub fn iter(&self) -> impl Iterator<Item = &str> + '_

Iterate token strings in snapshot order.
