Trait StorageAdapter 

Source 
pub trait StorageAdapter: Send + Sync {
    // Required methods
    fn get(&self, key: &str) -> StorageResult<Option<String>>;
    fn put(&self, key: &str, value: String) -> StorageResult<()>;
    fn del(&self, key: &str) -> StorageResult<()>;
    fn list(&self, prefix: &str) -> StorageResult<Vec<String>>;

    // Provided methods
    fn put_preserved(&self, key: &str, value: String) -> StorageResult<()> { ... }
    fn put_checkpoint(
        &self,
        key: &str,
        value: &StorageCheckpoint,
    ) -> StorageResult<()> { ... }
}

Required Methods§

Source

fn get(&self, key: &str) -> StorageResult<Option<String>>

Source

fn put(&self, key: &str, value: String) -> StorageResult<()>

Source

fn del(&self, key: &str) -> StorageResult<()>

Source

fn list(&self, prefix: &str) -> StorageResult<Vec<String>>

Provided Methods§

Source

fn put_preserved(&self, key: &str, value: String) -> StorageResult<()>

Preserve a migration input before a later checkpoint can replace it. Buffered adapters must commit this write before returning success.

Source

fn put_checkpoint( &self, key: &str, value: &StorageCheckpoint, ) -> StorageResult<()>

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
