pub fn peek(&self, key: &str) -> Option<&MemoryEntry>

Get an entry by key without updating access metadata.

pub fn delete(&mut self, key: &str) -> bool

Delete an entry. Returns true if the key existed.

pub fn all(&self) -> Vec<&MemoryEntry>

All entries, sorted by key.

pub fn by_tag(&self, tag: &str) -> Vec<&MemoryEntry>
