Struct opendal :: BlockingReader Copy item path

impl BlockingReader

pub fn read(&self, range: impl RangeBounds<u64>) -> Result<Buffer>

Read give range from reader into Buffer.

This operation is zero-copy, which means it keeps the [bytes::Bytes] returned by underlying storage services without any extra copy or intensive memory allocations.

§Notes

Buffer length smaller than range means we have reached the end of file.

pub fn read_into( &self, buf: &mut impl BufMut, range: impl RangeBounds<u64>, ) -> Result<usize>

This operation will copy and write bytes into given [BufMut]. Allocation happens while [BufMut] doesn’t have enough space.

§Notes

Returning length smaller than range means we have reached the end of file.

pub fn into_std_read(self, range: impl RangeBounds<u64>) -> Result<StdReader>

Convert reader into StdReader which implements [futures::AsyncRead], [futures::AsyncSeek] and [futures::AsyncBufRead].

pub fn into_bytes_iterator( self, range: impl RangeBounds<u64>, ) -> Result<StdBytesIterator>

Convert reader into StdBytesIterator which implements Iterator.
