Expand description

Describes an operation for performing byte-wise I/O on a block-based I/O stream.

See blocks_from_bytes() for more details.

Fields§

§byte_range_absolute: Range<usize>

The byte-wise range specified in absolute bytes from the beginning of an I/O stream. The size of this range should equal the size of bytes_in_block_range.

§block_range: Range<usize>

The range of blocks to transfer.

§bytes_in_block_range: Range<usize>

The range of bytes relative to the blocks specified by block_range. The size of this range should equal the size of byte_range_absolute.

For example, a range of 0..10 specifies that the first 10 bytes of the block_range are what should be transferred to/from the byte_range_absolute.
