A key/value store trait for basic ops.

Required methods

pub fn get(&self, key: impl AsRef<[u8]>) -> Result<Option<Vec<u8>>>

Gets a value for a key, if it exists.

pub fn set(
    &mut self,
    key: impl AsRef<[u8]>,
    value: impl AsRef<[u8]>
) -> Result<()>

Sets a value for a key, replacing the existing value if any.

pub fn remove(&mut self, key: impl AsRef<[u8]>) -> Result<()>

Removes a key, or does nothing if it does not exist.

pub fn contains(&mut self, key: impl AsRef<[u8]>) -> Result<bool>
