Struct ZipStorageAdapter 

pub struct ZipStorageAdapter<TStorage: ?Sized> { /* private fields */ }

A zip storage adapter.

Implementations

impl<TStorage: ?Sized + ReadableStorageTraits> ZipStorageAdapter<TStorage>

pub fn new( storage: Arc<TStorage>, key: StoreKey, ) -> Result<Self, ZipStorageAdapterCreateError>

Create a new zip storage adapter.

Errors

Returns a ZipStorageAdapterCreateError if the store value at key is not a valid zip file.

pub fn new_with_path<T: Into<PathBuf>>( storage: Arc<TStorage>, key: StoreKey, path: T, ) -> Result<Self, ZipStorageAdapterCreateError>

Create a new zip storage adapter to path within the zip file.

Errors

Returns a ZipStorageAdapterCreateError if the store value at key is not a valid zip file.
