pub struct MemoryObjectStore { /* private fields */ }

In-memory object store, suitable for unit tests and simulations.

Thread-safe via an Arc<Mutex<...>> interior.

Implementations

impl MemoryObjectStore

pub fn new() -> Self

Create an empty in-memory store.

pub fn len(&self) -> usize

Return the number of objects currently stored.

pub fn is_empty(&self) -> bool

Return true if the store is empty.

Trait Implementations

impl Clone for MemoryObjectStore

fn clone(&self) -> MemoryObjectStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for MemoryObjectStore

fn default() -> Self

Returns the “default value” for a type.

impl ObjectStore for MemoryObjectStore

fn put(&self, key: &ObjectKey, data: &[u8]) -> Result<()>

Store data under key, overwriting any existing object.

fn get(&self, key: &ObjectKey) -> Result<Vec<u8>>

Retrieve the object stored under key.

fn delete(&self, key: &ObjectKey) -> Result<()>

Delete the object at key. Returns Ok(()) if the key does not exist.

fn list(&self, prefix: &str) -> Result<Vec<ObjectMetadata>>

List all keys whose URI starts with prefix.

fn head(&self, key: &ObjectKey) -> Result<ObjectMetadata>

Return metadata for a single object without downloading its content.

fn exists(&self, key: &ObjectKey) -> bool

Check whether an object exists.

fn copy(&self, src: &ObjectKey, dst: &ObjectKey) -> Result<()>

Copy an object from src to dst within the same store.

fn rename(&self, src: &ObjectKey, dst: &ObjectKey) -> Result<()>

Rename/move an object from src to dst.
