Variants

Ident

ToTwoState

Convert a four-state value to two-state form. Unknown bits become zero: (value, mask) -> (value & !mask, 0).

Minus

BitNot

LogicNot

And

Or

Xor

PopCount

CountLeadingZeros

CountTrailingZeros

Implementations

impl UnaryOp

pub fn result_width(self, operand_width: usize) -> usize

Return the canonical result width for an operand of operand_width bits.

Bit-count operations return a value in 0..=operand_width, which needs ceil(log2(operand_width + 1)) bits. Computing that as the bit length of operand_width avoids overflowing when the operand width is usize::MAX.
