Struct bv::BitSlice
[−]
[src]
pub struct BitSlice<'a, Block> { /* fields omitted */ }
A slice of a bit-vector; akin to &'a [bool]
but packed.
Methods
impl<'a, Block: BlockType> BitSlice<'a, Block>
[src]
pub unsafe fn from_raw_parts(bits: *const Block, offset: u8, len: u64) -> Self
[src]
Creates a BitSlice
from a pointer to its data, an offset where the bits start, and the
number of available bits.
This is unsafe because the size of the passed-in buffer is not
checked. It must hold at least offset + len
bits or the resulting behavior is undefined.
pub fn from_slice(blocks: &'a [Block]) -> Self
[src]
Creates a BitSlice
from an array slice of blocks.
The size is always a multiple of
Block::nbits()
. If you want a different size, slice.
pub fn len(&self) -> u64
[src]
The number of bits in the slice.
pub fn is_empty(&self) -> bool
[src]
Returns whether there are no bits in the slice.
ⓘImportant traits for BitSliceBlockIter<'a, Block>pub fn block_iter(self) -> BitSliceBlockIter<'a, Block>
[src]
Gets an iterator over the blocks of the slice.
Note that this iterates over whole blocks, with a partial block only at the end. That
means that if the bit-slice offset is non-zero, these blocks may not correspond to the
blocks retrieved by BitVec::get_block
.
