Struct InMemory 

pub struct InMemory { /* private fields */ }

In-memory storage suitable for testing or for opting out of using a cloud storage provider.

Implementations

impl InMemory

pub fn new() -> Self

Create new in-memory storage.

pub fn fork(&self) -> Self

Creates a fork of the store, with the current content copied into the new store.

Trait Implementations

impl Clone for InMemory

fn clone(&self) -> InMemory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InMemory

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

Formats the value using the given formatter.

impl Default for InMemory

fn default() -> InMemory

Returns the “default value” for a type.

impl Display for InMemory

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

impl MultipartStore for InMemory

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

fn put_part<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _path: &'life1 Path, id: &'life2 MultipartId, part_idx: usize, payload: 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

fn 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,

Completes a multipart upload

fn abort_multipart<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _path: &'life1 Path, id: &'life2 MultipartId, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Aborts a multipart upload

impl ObjectStore for InMemory

fn list_with_delimiter<'life0, 'life1, 'async_trait>( &'life0 self, prefix: Option<&'life1 Path>, ) -> Pin<Box<dyn Future<Output = Result<ListResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The memory implementation returns all results, as opposed to the cloud versions which limit their results to 1k or more because of API limitations.

fn put_opts<'life0, 'life1, 'async_trait>( &'life0 self, location: &'life1 Path, payload: PutPayload, opts: PutOptions, ) -> Pin<Box<dyn Future<Output = Result<PutResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Save the provided payload to location with the given options

fn put_multipart_opts<'life0, 'life1, 'async_trait>( &'life0 self, location: &'life1 Path, opts: PutMultipartOptions, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn MultipartUpload>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Perform a multipart upload with options

fn get_opts<'life0, 'life1, 'async_trait>( &'life0 self, location: &'life1 Path, options: GetOptions, ) -> Pin<Box<dyn Future<Output = Result<GetResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn get_ranges<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, location: &'life1 Path, ranges: &'life2 [Range<u64>], ) -> Pin<Box<dyn Future<Output = Result<Vec<Bytes>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Return the bytes that are stored at the specified location in the given byte ranges

fn delete_stream( &self, locations: BoxStream<'static, Result<Path>>, ) -> BoxStream<'static, Result<Path>>

Delete all the objects at the specified locations

fn list(&self, prefix: Option<&Path>) -> BoxStream<'static, Result<ObjectMeta>>

List all the objects with the given prefix.

fn copy_opts<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, from: &'life1 Path, to: &'life2 Path, options: CopyOptions, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Copy an object from one path to another in the same object store.

fn list_with_offset( &self, prefix: Option<&Path>, offset: &Path, ) -> BoxStream<'static, Result<ObjectMeta>>
