Struct MultipartStateStore 

pub struct MultipartStateStore { /* private fields */ }

In-memory side-table mapping upload_id → context. One of these hangs off S4Service (always-on, no flag — the per-upload state is gateway-internal).

Implementations

impl MultipartStateStore

pub fn new() -> Self

Empty store. Use Arc<MultipartStateStore> so S4Service’s async handlers can borrow it across &self calls without requiring Clone.

pub fn put(&self, upload_id: &str, ctx: MultipartUploadContext)

Register a new upload under upload_id. If upload_id is already present (extremely unlikely — backend issues fresh ids) the previous entry is overwritten silently to mirror HashMap::insert’s replace-on-collision semantics.

pub fn get(&self, upload_id: &str) -> Option<MultipartUploadContext>

Snapshot the context for upload_id. None when no entry was registered (e.g. Complete arrived for an upload that the gateway has no record of — passes through to the backend untouched, which in turn surfaces NoSuchUpload).

pub fn remove(&self, upload_id: &str)

Drop the entry. Called by Complete / Abort to release the SSE-C key bytes and the tag-set memory promptly.

Trait Implementations

impl Default for MultipartStateStore

fn default() -> Self

Returns the “default value” for a type.
