Trait Implementations

impl<'a, V: KVPermissions<'a>> KVPermissions<'a> for VirtualKVPermissions<'a, V>

fn set_client(&self, client: &'a dyn KVClient)

Configure the client for operation callbacks.

fn get( &self, key: SubSliceMut<'static, u8>, value: SubSliceMut<'static, u8>, permissions: StoragePermissions, ) -> Result<(), (SubSliceMut<'static, u8>, SubSliceMut<'static, u8>, ErrorCode)>

Retrieve a value based on the given key.

fn set( &self, key: SubSliceMut<'static, u8>, value: SubSliceMut<'static, u8>, permissions: StoragePermissions, ) -> Result<(), (SubSliceMut<'static, u8>, SubSliceMut<'static, u8>, ErrorCode)>

Store a value based on the given key. If the key does not exist it will be added. If the key already exists the value will be updated.

fn add( &self, key: SubSliceMut<'static, u8>, value: SubSliceMut<'static, u8>, permissions: StoragePermissions, ) -> Result<(), (SubSliceMut<'static, u8>, SubSliceMut<'static, u8>, ErrorCode)>

Store a new value based on the given key. If the key does not exist it will be added. If the key already exists an error callback will be provided.

fn update( &self, key: SubSliceMut<'static, u8>, value: SubSliceMut<'static, u8>, permissions: StoragePermissions, ) -> Result<(), (SubSliceMut<'static, u8>, SubSliceMut<'static, u8>, ErrorCode)>

Modify a value based on the given key. If the key does not exist it an error callback will be provided.

fn delete( &self, key: SubSliceMut<'static, u8>, permissions: StoragePermissions, ) -> Result<(), (SubSliceMut<'static, u8>, ErrorCode)>

Delete a key-value object based on the given key.

fn header_size(&self) -> usize

Returns the length of the key-value store’s header in bytes.
