Struct EphemeralNonVolatileStore

pub struct EphemeralNonVolatileStore(/* private fields */);

An ephemeral implementation of NonVolatileStore backed by an in-memory buffer. Useful for tests, stateless VM scenarios.

Implementations

impl EphemeralNonVolatileStore

pub fn new_boxed() -> Box<dyn NonVolatileStore>

Shortcut to create a Box<dyn NonVolatileStore> backed by an EphemeralNonVolatileStore.

Trait Implementations

impl Default for EphemeralNonVolatileStore

fn default() -> EphemeralNonVolatileStore

Returns the “default value” for a type.

impl NonVolatileStore for EphemeralNonVolatileStore

fn persist<'life0, 'async_trait>( &'life0 mut self, data: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<(), NonVolatileStoreError>> + Send + 'async_trait>>

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

Write data to a non-volatile storage medium.

fn restore<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, NonVolatileStoreError>> + Send + 'async_trait>>

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

Read any previously written data. Returns None if no data exists.
