Trait FileRead 

pub trait FileRead:
    Send
    + Sync
    + Unpin
    + 'static {
    // Required method
    fn read<'life0, 'async_trait>(
        &'life0 self,
        range: Range<u64>,
    ) -> Pin<Box<dyn Future<Output = Result<Bytes>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Trait for reading file.

TODO

It’s possible for us to remove the async_trait, but we need to figure out how to handle the object safety.

Required Methods

fn read<'life0, 'async_trait>( &'life0 self, range: Range<u64>, ) -> Pin<Box<dyn Future<Output = Result<Bytes>> + Send + 'async_trait>>

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

Read file content with given range.

TODO: we can support reading non-contiguous bytes in the future.

Dyn Compatibility

This trait is dyn compatible.

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