Required Methods§

Source

fn put<'life0, 'async_trait>( &'life0 self, hash: Hash, data: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<bool, StoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Store data by its hash Returns true if newly stored, false if already existed

Source

fn get<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 Hash, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, StoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieve data by hash Returns data or None if not found

Source

fn has<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 Hash, ) -> Pin<Box<dyn Future<Output = Result<bool, StoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Check if hash exists

Source

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 Hash, ) -> Pin<Box<dyn Future<Output = Result<bool, StoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete by hash Returns true if deleted, false if didn’t exist
