Function bitwise::word::reverse_byte_groups

pub fn reverse_byte_groups<T: Word, U: UnsignedWord>(x: T,
                                                     group_byte_size: U,
                                                     no_subwords: U)
                                                     -> T

Reverses groups of bytes within each subword of x

• group_byte_size - The size (in bytes) of the groups of bytes to be reversed.
• no_subwords - The number of subwords in x.

The word x is divided into no_subwords. The byte groups of size group_byte_size are reversed within each subword. Bits within a byte group are not reversed.

The size in bits of a subword is thus x::bit_size() / no_subword. When no_suboword == 1 the subword equals the original word. When group_byte_size == 1 bytes are reversed within a subword.

Examples

use bitwise::word::*;

// Single bytes:
assert_eq!(0b0101_1101_1010_0101_u16.reverse_byte_groups(1u32, 1u32), 0b1010_0101_0101_1101u16);

// Single bytes within two half-words:
assert_eq!(reverse_byte_groups(0b0101_1101_1010_0101_0101_1101_1010_0101u32, 1u32, 2u32), 0b1010_0101_0101_1101_1010_0101_0101_1101u32);
