Struct State

struct State {
    transitions: Vec<Transition>,
}

A single state in this trie.

Fields

transitions: Vec<Transition>

A sorted sequence of non-overlapping transitions to other states. Each transition corresponds to a single range of bytes.

Implementations

impl State

fn find(&self, range: Utf8Range) -> usize

Find the position at which the given range should be inserted in this state.

The position returned is always in the inclusive range [0, transitions.len()]. If ‘transitions.len()’ is returned, then the given range overlaps with no other range in this state and is greater than all of them.

For all other possible positions, the given range either overlaps with the transition at that position or is otherwise less than it with no overlap (and is greater than the previous transition). In the former case, careful attention must be paid to inserting this range as a new transition. In the latter case, the range can be inserted as a new transition at the given position without disrupting any other transitions.

fn clear(&mut self)

Clear this state such that it has zero transitions.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for State

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
