pub struct ByteReaderWriterWrapper<RW: BlockReader + BlockWriter>(_);
Expand description

A wrapper struct that implements a byte-wise reader and writer atop a block-based reader and writer.

This ideally should be realized via automatic trait implementations, in which all types that implement BlockReader + BlockWriter also implement ByteReader + ByteWriter, but we cannot do that because Rust currently does not support specialization.

Example

Use the From implementation around a BlockReader + BlockWriter instance, such as:

// Assume `storage_dev` implements `BlockReader + BlockWriter`
let mut reader_writer = ByteReaderWriterWrapper::from(storage_dev); 
let bytes_read = reader_writer.read_at(...);
let bytes_written = reader_writer.write_at(...);

Reads blocks of data from this reader into the given buffer. Read more
Writes blocks of data from the given buffer to this writer. Read more
Flushes this entire writer’s output stream, ensuring all contents in intermediate buffers are fully written out. Read more

Converts to this type from the input type.
Returns the length (size in bytes) of this I/O stream or device.
