Trait ObjectStreamReader

Provider-neutral read port. Implementations must produce bounded chunks and stop provider reads when the returned stream is dropped.

Required Methods

fn head<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 ObjectKey, ) -> Pin<Box<dyn Future<Output = Result<Option<ObjectReadHead>, ObjectStoreError>> + Send + 'async_trait>>

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

fn read<'life0, 'async_trait>( &'life0 self, request: ObjectReadRequest, ) -> Pin<Box<dyn Future<Output = Result<Option<ObjectReadResponse>, ObjectStoreError>> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is dyn compatible.

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