Errors

Returns an error if the session directory cannot be created

pub fn find_prefix_session( &self, text: &str, tokens: &[i32], ) -> Option<(usize, Arc<SessionData>)>

pub fn register_prefix( &self, text: &str, tokens: &[i32], session_data: Vec<u8>, ) -> Result<()>

Register a new prefix for caching

Errors

Returns an error if the cache is full and cannot evict enough entries

pub fn analyze(&self, tokens: &[i32]) -> Option<usize>

Analyze text for caching opportunities

pub fn clear(&self)
