[−][src]Trait orga::store::Write

pub trait Write {
    fn put(&mut self, key: Vec<u8>, value: Vec<u8>) -> Result<()>;

    fn delete(&mut self, key: &[u8]) -> Result<()>;

    fn as_mut<'a>(&'a mut self) -> &'a mut Self { ... }
}

Trait for write access to key/value stores.

Required methods

fn put(&mut self, key: Vec<u8>, value: Vec<u8>) -> Result<()>

Writes a key and value to the store.

If a value already exists for the given key, implementations should overwrite the value.

fn delete(&mut self, key: &[u8]) -> Result<()>

Deletes the value with the given key.

If no value exists for the given key, implementations should treat the operation as a no-op (but may still issue a call to delete to an underlying store).

Provided methods

fn as_mut<'a>(&'a mut self) -> &'a mut Self

Returns a mutable reference to the store.
