42 public declarations

and&T -> &T -> T where T: Bits
Both values' bits, kept where both are set.
fn
bit&T -> Int -> T where T: Bits
A value with only the bit at a position set, or nought when the position is
fn
bits&T -> Array[Bool] where T: Bits
The bits of a value, lowest position first, over the type's own width.
fn
Bits
A type whose values are bit patterns.
trait
clearBit&T -> Int -> T where T: Bits
The value with one bit cleared.
fn
complement&T -> T where T: Bits
Every bit inverted, over the type's own width.
fn
countLeadingZeros&T -> Int where T: Bits
How many high positions are clear before the first set bit. A value with no
fn
countTrailingZeros&T -> Int where T: Bits
How many low positions are clear before the first set bit.
fn
extract&T -> Int -> Int -> T where T: Bits
The bits at positions `from` up to but not including `to`, moved down.
fn
flipBit&T -> Int -> T where T: Bits
The value with one bit inverted.
fn
highestSetBit&T -> Option[Int] where T: Bits
The position of the highest set bit, or `None` when no bit is set.
fn
isSingleBit&T -> Bool where T: Bits
Whether a value has exactly one bit set, which is what a power of two is.
fn
lowestSetBit&T -> Option[Int] where T: Bits
The position of the lowest set bit, or `None` when no bit is set.
fn
mask&T -> Int -> T where T: Bits
The value with its low `width` bits kept and the rest cleared.
fn
nextPowerOfTwo&T -> T where T: Bits
The smallest power of two that is not below the value.
fn
ones&T -> T where T: Bits
A value with every bit set, of the same type as the example given.
fn
or&T -> &T -> T where T: Bits
Both values' bits, kept where either is set.
fn
popCount&T -> Int where T: Bits
How many bits are set, counted over the type's own width.
fn
rotateLeft&T -> Int -> T where T: Bits
The bits moved toward the high end, with the ones that leave reappearing at
fn
rotateRight&T -> Int -> T where T: Bits
The bits moved toward the low end, with the ones that leave reappearing at
fn
setBit&T -> Int -> T where T: Bits
The value with one bit set.
fn
shiftLeft&T -> Int -> T where T: Bits
The bits moved toward the high end, filling with noughts.
fn
shiftRight&T -> Int -> T where T: Bits
The bits moved toward the low end. A signed type keeps its sign; an unsigned
fn
testBit&T -> Int -> Bool where T: Bits
Whether the bit at a position is set. A position outside the type is not.
fn
toBinary&T -> Str where T: Bits
The value written in binary, without a sign or a prefix, over the type's own
fn
toHex&T -> Str where T: Bits
The value written in lower-case hexadecimal, without a prefix.
