Struct NoUploads 

pub struct NoUploads;

A store for declarations without uploads, which refuses any upload.

A declaration without uploads accepts handles of every type, so it can be read with this store, whose handle is (). If the declaration does have uploads of Upload<()>, an upload fails to store with NoUploadsError.

Trait Implementations

impl Clone for NoUploads

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NoUploads

impl Debug for NoUploads

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

Formats the value using the given formatter.

impl Default for NoUploads

fn default() -> Self

Returns the “default value” for a type.

impl UploadStore for NoUploads

type Handle = ()

What the declared struct holds for a stored upload, such as a path.

type Upload = ()

An upload being stored.

type Error = NoUploadsError

Why a store operation failed.

async fn create( &mut self, _: &UploadHead, _: &Cancellation, ) -> Result<(), NoUploadsError>

Begin storing an upload. When this fails, nothing of the upload is stored.

async fn write( &mut self, _: &mut (), _: &[u8], _: &Cancellation, ) -> Result<(), NoUploadsError>

Store some of an upload’s content, after what was stored before. When this fails, the caller must abort the upload, as read_content does.

async fn finish( &mut self, _: &mut (), _: &Cancellation, ) -> Result<(), NoUploadsError>

Complete an upload whose content has all been written, returning its handle. When this fails, the caller must abort the upload, as read_content does.

async fn abort(&mut self, _: ()) -> Result<(), NoUploadsError>

Remove whatever was stored of an upload that was not finished, or whose finish failed. It is not cancellable, since it cleans up after a failure.

async fn remove(&mut self, _: ()) -> Result<(), NoUploadsError>

Remove a finished upload. It is not cancellable, since it cleans up after a failure.
