Trait bv::BitVecMut
[−]
[src]
pub trait BitVecMut: BitVec { fn set_bit(&mut self, position: u64, value: bool) { ... } fn set_block(&mut self, position: usize, value: Self::Block) { ... } fn set_bits(&mut self, start: u64, count: usize, value: Self::Block) { ... } }
Mutable bit vector operations that don’t affect the length.
Minimal complete definition is set_bit
or set_block
, since each
is defined in terms of the other. Note that set_block
in terms of
set_bit
is inefficient, and thus you should implement set_block
directly if possible.
Provided Methods
fn set_bit(&mut self, position: u64, value: bool)
Sets the bit at position
to value
.
The default implementation uses get_block
and set_block
.
Panics
Panics if position
is out of bounds.
fn set_block(&mut self, position: usize, value: Self::Block)
Sets the block at position
to value
.
The bits are laid out Block::nbits()
per block, with the notional
zeroth bit in the least significant position. If self.bit_len()
is
not a multiple of Block::nbits()
then the last block will
contain extra bits that are not part of the bit vector. Implementations
of set_block
should not change those trailing bits.
The default implementation sets a block by setting each of its bits in turn. Consider it a slow reference implementation, and override it.
Panics
Panics if position
is out of bounds.
fn set_bits(&mut self, start: u64, count: usize, value: Self::Block)
Sets count
bits starting at bit index start
, interpreted as a
little-endian integer.
Panics
Panics if the bit span goes out of bounds.
