    // Provided method
    fn contains(&self, key: &[u8]) -> StorageResult<bool> { ... }
}

Abstraction over key-value storage backends.

This trait allows rpytest to use different storage implementations (e.g., sled, redb) without changing the core logic.

Required Methods

fn open(path: &Path) -> StorageResult<Self>

where Self: Sized,

Open or create a storage instance at the given path.

fn get(&self, key: &[u8]) -> StorageResult<Option<Vec<u8>>>

Get a value by key.

fn set(&self, key: &[u8], value: &[u8]) -> StorageResult<()>

Set a key-value pair.

fn delete(&self, key: &[u8]) -> StorageResult<()>

Delete a key.

fn flush(&self) -> StorageResult<()>

Flush pending writes to disk.

fn scan_prefix(&self, prefix: &[u8]) -> StorageResult<Vec<(Vec<u8>, Vec<u8>)>>

Iterate over all keys with a given prefix.

fn clear(&self) -> StorageResult<()>

Clear all data (use with caution).

Provided Methods

fn contains(&self, key: &[u8]) -> StorageResult<bool>

Check if a key exists.
