Expand description
§Exclusive Bit-Slice Chunking
This iterator yields successive non-overlapping mutable chunks of a bit-slice. Chunking advances one subslice at a time, starting at the beginning of the bit-slice.
If the original bit-slice’s length is not evenly divided by the chunk width, then the final chunk will be the remainder, and will be shorter than requested.
It is created by the BitSlice::chunks_mut
method.
§Original
§API Differences
This iterator marks all yielded bit-slices as ::Alias
ed.
§Examples
use bitvec::prelude::*;
let bits = bits![mut 0, 0, 0, 1, 1, 1, 0, 1];
let mut chunks = unsafe {
bits.chunks_mut(3).remove_alias()
};
chunks.next().unwrap().fill(true);
chunks.next().unwrap().fill(false);
chunks.next().unwrap().copy_from_bitslice(bits![1, 0]);
assert!(chunks.next().is_none());
assert_eq!(bits, bits![1, 1, 1, 0, 0, 0, 1, 0]);
Implementations§
Source§impl<'a, T, O> ChunksMut<'a, T, O>
impl<'a, T, O> ChunksMut<'a, T, O>
Sourcepub unsafe fn remove_alias(self) -> ChunksMutNoAlias<'a, T, O> ⓘ
pub unsafe fn remove_alias(self) -> ChunksMutNoAlias<'a, T, O> ⓘ
Removes a layer of ::Alias
tainting from the yielded item.
§Safety
You must consume the adapted iterator in a loop that does not allow multiple yielded items to exist in the same scope. Each yielded item must have a completely non-overlapping lifetime from all the others.
The items yielded by this iterator will not have an additional alias marker applied to them, so their use in an iteration sequence will not be penalized when the surrounding code ensures that each item yielded by the iterator is destroyed before the next is produced.
This adapter does not convert the iterator to use the
T::Mem
raw underlying type, as it can be applied to an
iterator over an already-aliased bit-slice and must preserve the
initial condition. Its only effect is to remove the additional
T::Alias
marker imposed by the mutable iterators.
Violating this requirement causes memory-unsafety and breaks Rust’s data-race guarantees.
