Generic helper methods to treat [u*]-slices as big endian bit strings.
Required Methods
fn mask(ndx: usize) -> Self
integer with single bit set. bit 0 is the highest bit (big
endian). Wraps at Self::elembits().
fn inc(slice: &mut [Self], prefix: usize) -> bool
increment from right; don't touch first prefix bits; returns
true on overflow
Panics
Panics if prefix > Self::elembits() * slice.len().
fn get(slice: &[Self], ndx: usize) -> bool
fn on(slice: &mut [Self], ndx: usize)
fn off(slice: &mut [Self], ndx: usize)
fn flip(slice: &mut [Self], ndx: usize)
Length of the longest shared prefix of two bit strings.
fn set_false_from(slice: &mut [Self], ndx: usize)
Set all bits from [ndx..] to false.
Doesn't do anything if ndx >= Self::elembits() * slice.len().
fn is_false_from(slice: &[Self], ndx: usize) -> bool
Whether all bits from [ndx..] are false.
Returns true if ndx >= Self::elembits() * slice.len().
fn set_true_from(slice: &mut [Self], ndx: usize)
Set all bits from [ndx..] to true.
Doesn't do anything if ndx >= Self::elembits() * slice.len().
fn is_true_from(slice: &[Self], ndx: usize) -> bool
Whether all bits from [ndx..] are true.
Returns true if ndx >= Self::elembits() * slice.len().
fn contains(slice: &[Self], prefix: usize, other: &[Self]) -> bool
check whether another bit string other shares the first
prefix bits with self
