Struct LocalObjectReader 

pub struct LocalObjectReader { /* private fields */ }

Object reader for local file system.

Implementations

impl LocalObjectReader

pub async fn open_local_path( path: impl AsRef<Path>, block_size: usize, known_size: Option<usize>, ) -> Result<Box<dyn Reader>>

pub async fn open( path: &Path, block_size: usize, known_size: Option<usize>, ) -> Result<Box<dyn Reader>>

Open a local object reader, with default prefetch size.

For backward compatibility with existing code that doesn’t need tracking.
