Extension trait for block stores with streaming capabilities

Provided Methods§

Source

fn get_range<'life0, 'life1, 'async_trait>( &'life0 self, cid: &'life1 Cid, range: ByteRange, ) -> Pin<Box<dyn Future<Output = Result<Option<PartialBlock>>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Read a partial block (range-based)

This allows efficient access to portions of large blocks without loading the entire block into memory.

Source

fn reader<'life0, 'life1, 'async_trait>( &'life0 self, cid: &'life1 Cid, ) -> Pin<Box<dyn Future<Output = Result<Option<BlockReader>>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Create an async reader for a block

Source

fn get_size<'life0, 'life1, 'async_trait>( &'life0 self, cid: &'life1 Cid, ) -> Pin<Box<dyn Future<Output = Result<Option<u64>>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get the size of a block without reading its contents

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
