Struct CaseFoldPool 

pub struct CaseFoldPool { /* private fields */ }

A string pool that normalizes strings to lowercase before interning, enabling case-insensitive comparisons via cheap integer equality.

Implementations

impl CaseFoldPool

pub fn new() -> Self

Create an empty case-folding pool.

pub fn intern(&mut self, s: &str) -> InternedString

Intern a string after folding to lowercase.

pub fn resolve(&self, id: InternedString) -> Option<&str>

Resolve back to the canonicalized (lowercase) form.

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

Check whether the lowercase version of s has been interned.

pub fn len(&self) -> usize

Number of unique strings.

pub fn is_empty(&self) -> bool

Whether the pool is empty.

pub fn inner(&self) -> &StringPool

Access the inner pool.
