Required Methods

fn get(&self, key: &Key) -> Option<Value>

fn put_with_option( &mut self, key: &Key, value: &Value, option: Option<PutOption>, ) -> Result<(), BitCaskError>

fn delete(&mut self, key: &Key) -> Result<(), BitCaskError>

fn size(&self) -> usize

Provided Methods

fn put(&mut self, key: &Key, value: &Value) -> Result<(), BitCaskError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
