Trait Read 

pub trait Read:
    Unpin
    + Send
    + Sync {
    // Required methods
    fn open(
        &self,
        range: BytesRange,
    ) -> impl Future<Output = Result<(RpRead, Box<dyn ReadStreamDyn>)>> + MaybeSend;
    fn read(
        &self,
        range: BytesRange,
    ) -> impl Future<Output = Result<(RpRead, Buffer)>> + MaybeSend;
}

Read is the internal trait used by OpenDAL to read ranges from storage.

Users should not use or import this trait unless they are implementing a Service.

This trait returns impl Future, so it is not object safe. Use ReadDyn when type erasure is required.

Required Methods

fn open( &self, range: BytesRange, ) -> impl Future<Output = Result<(RpRead, Box<dyn ReadStreamDyn>)>> + MaybeSend

Open a range stream for the given range.

fn read( &self, range: BytesRange, ) -> impl Future<Output = Result<(RpRead, Buffer)>> + MaybeSend

Read an exact bounded range into Buffer.

Dyn Compatibility

This trait is not dyn compatible.

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

Implementations on Foreign Types

impl Read for ()

async fn open( &self, range: BytesRange, ) -> Result<(RpRead, Box<dyn ReadStreamDyn>)>
