Lane-wise generalization of bool for SIMD booleans.

This trait implemented by bool as well as SIMD boolean types like packed_simd::m32x4. It is designed to abstract the behavior of booleans so it can work with multi-lane boolean values in an AoSoA setting.

Required methods

fn bitmask(self) -> u64

A bit mask representing the boolean state of each lanes of self.

The i-th bit of the result is 1 iff. the i-th lane of self is true.

fn and(self) -> bool

Lane-wise bitwise and of the vector elements.

fn or(self) -> bool

Lane-wise bitwise or of the vector elements.

fn xor(self) -> bool

Lane-wise bitwise xor of the vector elements.

fn all(self) -> bool

Are all vector lanes true?

fn any(self) -> bool

Is any vector lane true?

fn none(self) -> bool

Are all vector lanes false?

fn if_else<Res: SimdValue<SimdBool = Self>>(
    self,
    if_value: impl FnOnce() -> Res,
    else_value: impl FnOnce() -> Res
) -> Res

Merges the value of if_value() and else_value() depending on the lanes of self.

  • For each lane of self containing 1, the result will contain the corresponding lane of if_value().
  • For each lane of self containing 0, the result will contain the corresponding lane of else_value().

The implementor of this trait is free to choose on what cases if_value and else_value are actually called.

fn if_else2<Res: SimdValue<SimdBool = Self>>(
    self,
    if_value: impl FnOnce() -> Res,
    else_if: (impl FnOnce() -> Self, impl FnOnce() -> Res),
    else_value: impl FnOnce() -> Res
) -> Res

Merges the value of if_value() and else_if.1() and else_value() depending on the lanes of self and else_if.0().

  • For each lane of self containing 1, the result will contain the corresponding lane of if_value().
  • For each lane of self containing 0 but with a corresponding lane of else_if.0() containing 1, the result will contain the corresponding lane of else_if.1().
  • For each lane of self containing 0 but with a corresponding lane of else_if.0() containing 0, the result will contain the corresponding lane of else_value().

The implementor of this trait is free to choose on what cases any of those closures are implemented.

fn if_else3<Res: SimdValue<SimdBool = Self>>(
    self,
    if_value: impl FnOnce() -> Res,
    else_if: (impl FnOnce() -> Self, impl FnOnce() -> Res),
    else_else_if: (impl FnOnce() -> Self, impl FnOnce() -> Res),
    else_value: impl FnOnce() -> Res
) -> Res

Merges the value of if_value() and else_if.1() and else_else_if.1() and else_value() depending on the lanes of self and else_if.0() and else_else_if.0().

  • For each lane of self containing 1, the result will contain the corresponding lane of if_value().
  • For each lane of self containing 0 but with a corresponding lane of else_if.0() containing 1, the result will contain the corresponding lane of else_if.1().
  • For each lane of self containing 0 and else_if.0() containing 0 and else_else_if.0() containing 1, the result will contain the corresponding lane of else_else_if.1().
  • Other lanes will contain the corresponding lane of else_value().

The implementor of this trait is free to choose on what cases any of those closures are implemented.
