Implementations

impl CloudObjectReader

pub fn new( object_store: Arc<dyn ObjectStore>, path: Path, block_size: usize, known_size: Option<usize>, download_retry_count: usize, ) -> Result<Self>

Create an ObjectReader from URI

Trait Implementations

impl Debug for CloudObjectReader

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

Formats the value using the given formatter.

impl DeepSizeOf for CloudObjectReader

fn deep_size_of_children(&self, context: &mut Context) -> usize

Returns an estimation of the heap-managed storage of this object. This does not include the size of the object itself.

fn deep_size_of(&self) -> usize

Returns an estimation of a total size of memory owned by the object, including heap-managed storage.

impl Reader for CloudObjectReader

fn size<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<usize>> + Send + 'async_trait>>

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

Object/File Size.

fn path(&self) -> &Path

fn block_size(&self) -> usize

Suggest optimal I/O size per storage device.

fn io_parallelism(&self) -> usize

Suggest optimal I/O parallelism per storage device.

fn get_range<'life0, 'async_trait>( &'life0 self, range: Range<usize>, ) -> Pin<Box<dyn Future<Output = OSResult<Bytes>> + Send + 'async_trait>>

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

Read a range of bytes from the object.

fn get_all<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = OSResult<Bytes>> + Send + 'async_trait>>

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

Read all bytes from the object.
