    fn is_empty(&self) -> bool { ... }
}

Bounded, random-access reader used across application and object-store ports. Implementations must never return more than max_bytes.

Required Methods

fn len(&self) -> u64

fn digest(&self) -> &str

fn read_chunk<'life0, 'async_trait>( &'life0 self, offset: u64, max_bytes: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>>> + Send + 'async_trait>>

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

Provided Methods

fn is_empty(&self) -> bool

Dyn Compatibility

This trait is dyn compatible.

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