Expand description

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§

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.

Lane-wise bitwise and of the vector elements.

Lane-wise bitwise or of the vector elements.

Lane-wise bitwise xor of the vector elements.

Are all vector lanes true?

Is any vector lane true?

Are all vector lanes false?

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.

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.

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.
