Required Methods§

Source

fn open<'life0, 'async_trait>( &'life0 mut self, label: String, ) -> Pin<Box<dyn Future<Output = Result<Result<Resource<Store>, Error>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Open the store with the specified label.

label must refer to a store allowed in the spin.toml manifest.

error::no-such-store will be raised if the label is not recognized.

Source

fn get<'life0, 'async_trait>( &'life0 mut self, self_: Resource<Store>, key: String, ) -> Pin<Box<dyn Future<Output = Result<Result<Option<Vec<u8>>, Error>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Get the value associated with the specified key

Returns ok(none) if the key does not exist.

Source

fn set<'life0, 'async_trait>( &'life0 mut self, self_: Resource<Store>, key: String, value: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<Result<(), Error>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Set the value associated with the specified key overwriting any existing value.

Source

fn delete<'life0, 'async_trait>( &'life0 mut self, self_: Resource<Store>, key: String, ) -> Pin<Box<dyn Future<Output = Result<Result<(), Error>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Delete the tuple with the specified key

No error is raised if a tuple did not previously exist for key.

Source

fn exists<'life0, 'async_trait>( &'life0 mut self, self_: Resource<Store>, key: String, ) -> Pin<Box<dyn Future<Output = Result<Result<bool, Error>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Return whether a tuple exists for the specified key

Source

fn get_keys<'life0, 'async_trait>( &'life0 mut self, self_: Resource<Store>, ) -> Pin<Box<dyn Future<Output = Result<Result<Vec<String>, Error>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Return a list of all the keys

Source

fn drop<'life0, 'async_trait>( &'life0 mut self, rep: Resource<Store>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,
