Struct AsyncCache 

pub struct AsyncCache { /* private fields */ }

Handle to a cache database.

Implementations

impl AsyncCache

pub async fn new(kind: CacheKind) -> Result<Self, CacheError>

Create new cache handle of a given kind.

Trait Implementations

impl CacheRaw for AsyncCache

fn get_field<'life0, 'life1, 'async_trait>( &'life0 mut self, field: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, CacheError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieves a field’s value from the cache.

fn get_fields<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<HashMap<String, Vec<u8>>, CacheError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Retrieves all fields and their values for a given key from the cache.

fn insert_field<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, field: &'life1 str, value: &'life2 [u8], ) -> Pin<Box<dyn Future<Output = Result<bool, CacheError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Adds a field with given value to the cache. Returns true if an element was added,false if it existed before and was updated.

fn field_exists<'life0, 'life1, 'async_trait>( &'life0 mut self, field: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<bool, CacheError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Checks if a specific field exists in the cache.

fn delete_field<'life0, 'life1, 'async_trait>( &'life0 mut self, field: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<bool, CacheError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Deletes field from the cache. Returns true if that entry existed.

impl Clone for AsyncCache

fn clone(&self) -> AsyncCache

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
