Struct automata::regex::Cached

pub struct Cached<A: Alphabet> { /* fields omitted */ }

Provides access to creating new regex expressions with cached results.

Methods

impl<A: Alphabet> Cached<A>

pub fn new() -> Self

pub fn insert(&mut self, op: Op<A>) -> Handle

Insert a new operation.

Deduplicates same operations to also point to the same handle, so you can not generally assert that the returned handle is the new root of the regex.

pub fn inner(&self) -> &Regex<A>

Access the inner regex.

pub fn into_inner(self) -> Regex<A>

Turn it into a raw regex again.

pub fn fill_cache(&mut self)

Fill the cache from all subexpressions in the regex.

The cache would normally only take into account all newly added Ops. For modifying an existing regex this will fill the cache with all already inserted subexpressions.

Trait Implementations
