Struct RegexPool 

pub struct RegexPool { /* private fields */ }

Thread-safe, size-bounded FIFO cache for compiled Regex objects.

Most useful in daemon mode where the same patterns are queried repeatedly. Set max_entries to 0 for unlimited capacity.

pub fn get_or_compile(&self, pattern: &str) -> Result<Regex, Error>

Returns a compiled Regex for the given pattern, using the cached copy if available.

Errors

Returns regex::Error if the pattern fails to compile.

pub fn invalidate(&self, pattern: &str)

Removes a specific pattern from the pool.

pub fn clear(&self)

Clears all entries from the pool.

pub fn stats(&self) -> PoolStats

pub fn len(&self) -> usize

Returns the number of cached patterns.

pub fn is_empty(&self) -> bool

Returns true if the pool contains no entries.
