Struct io::BlockByteTransfer

pub struct BlockByteTransfer {
    pub byte_range_absolute: Range<usize>,
    pub block_range: Range<usize>,
    pub bytes_in_block_range: Range<usize>,
}

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.
