Struct InMemoryObjectStore 

pub struct InMemoryObjectStore { /* private fields */ }

An in-memory ObjectClient with real ETag and conditional-write semantics, for building and testing the object-storage backend without a cloud dependency.

Implementations

impl InMemoryObjectStore

pub fn new() -> Self

Creates an empty in-memory object store.

Trait Implementations

impl Debug for InMemoryObjectStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemoryObjectStore

fn default() -> InMemoryObjectStore

Returns the “default value” for a type.

impl ObjectClient for InMemoryObjectStore

fn get<'op>(&'op self, key: &str) -> ObjectFuture<'op, Option<Arc<[u8]>>>

Reads the whole object, or None when the key is absent.

fn get_range<'op>( &'op self, key: &str, offset: u64, len: u64, ) -> ObjectFuture<'op, Arc<[u8]>>

Reads len bytes starting at offset; errors for an absent key or an out-of-bounds range.

fn put<'op>(&'op self, key: &str, bytes: Arc<[u8]>) -> ObjectFuture<'op, ETag>

Stores the object unconditionally, returning its new ETag.

fn delete<'op>(&'op self, key: &str) -> ObjectFuture<'op, ()>

Deletes the object (idempotent: deleting an absent key succeeds).

fn list<'op>(&'op self, prefix: &str) -> ObjectFuture<'op, Vec<ObjectMeta>>

Lists objects whose key starts with prefix, in key order.

fn head<'op>(&'op self, key: &str) -> ObjectFuture<'op, Option<ObjectMeta>>

Returns the object’s metadata (size + ETag) without its bytes, or None when the key is absent (like S3 HEAD).

fn put_if<'op>( &'op self, key: &str, bytes: Arc<[u8]>, precondition: Precondition, ) -> ObjectFuture<'op, PutIf>

Conditional write (compare-and-swap): stores bytes only if precondition holds, otherwise reports PutIf::PreconditionFailed with the current ETag. This is the manifest commit point; it must be a real CAS.
