Expand description
A low-level interface for interacting with multipart upload APIs
Most use-cases should prefer ObjectStore::put_multipart
as this is supported by more
backends, including LocalFileSystem
, and automatically handles uploading fixed
size parts of sufficient size in parallel
Required Methods§
sourcefn create_multipart<'life0, 'life1, 'async_trait>(
&'life0 self,
path: &'life1 Path,
) -> Pin<Box<dyn Future<Output = Result<MultipartId>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
fn create_multipart<'life0, 'life1, 'async_trait>(
&'life0 self,
path: &'life1 Path,
) -> Pin<Box<dyn Future<Output = Result<MultipartId>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
Creates a new multipart upload, returning the MultipartId
sourcefn put_part<'life0, 'life1, 'life2, 'async_trait>(
&'life0 self,
path: &'life1 Path,
id: &'life2 MultipartId,
part_idx: usize,
data: PutPayload,
) -> Pin<Box<dyn Future<Output = Result<PartId>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
'life2: 'async_trait,
fn put_part<'life0, 'life1, 'life2, 'async_trait>(
&'life0 self,
path: &'life1 Path,
id: &'life2 MultipartId,
part_idx: usize,
data: PutPayload,
) -> Pin<Box<dyn Future<Output = Result<PartId>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
'life2: 'async_trait,
Uploads a new part with index part_idx
part_idx
should be an integer in the range 0..N
where N
is the number of
parts in the upload. Parts may be uploaded concurrently and in any order.
Most stores require that all parts excluding the last are at least 5 MiB, and some
further require that all parts excluding the last be the same size, e.g. R2.
WriteMultipart
performs writes in fixed size blocks of 5 MiB, and clients wanting
to maximise compatibility should look to do likewise.
sourcefn complete_multipart<'life0, 'life1, 'life2, 'async_trait>(
&'life0 self,
path: &'life1 Path,
id: &'life2 MultipartId,
parts: Vec<PartId>,
) -> Pin<Box<dyn Future<Output = Result<PutResult>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
'life2: 'async_trait,
fn complete_multipart<'life0, 'life1, 'life2, 'async_trait>(
&'life0 self,
path: &'life1 Path,
id: &'life2 MultipartId,
parts: Vec<PartId>,

Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
'life2: 'async_trait,
Completes a multipart upload
The i
’th value of parts
must be a PartId
returned by a call to Self::put_part
with a part_idx
of i
, and the same path
and id
as provided to this method. Calling
this method with out of sequence or repeated PartId
, or PartId
returned for other
values of path
or id
, will result in implementation-defined behaviour
sourcefn abort_multipart<'life0, 'life1, 'life2, 'async_trait>(
