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 an Accessor.

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", so this trait is not object safe.

Implementations on Foreign Types

impl Read for ()

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

async fn read(&self, _: BytesRange) -> Result<(RpRead, Buffer)>

impl<T: ReadDyn + ?Sized> Read for Box<T>

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

async fn read(&self, range: BytesRange) -> Result<(RpRead, Buffer)>
