Multiply BVecN and VecN? Implement Into/From for BVecN to VecN with 1.0:s and 0.0:s about glam-rs HOT 1 CLOSED

For the most part I only support behaviour that is supported in Rust itself. Rust will not let you multiple a f32 or i32 by a bool.

1.0_f32 * true // compile error
1.0_f32 * f32::from(true) // ok

What it does support is a from conversion from bool to float or bool to integer.

1.0_f32 * f32::from(true) // ok

glam also has from impls for creating a Vec3 or IVec3 from a BVec3 or BVec3A, so while what you are proposing won't work the following will

Vec3A::from(BVec3A) * Vec3A, Vec3::from(BVec3) * Vec3, IVec3::from(BVec3) * IVec3, I16Vec3::from(BVec3) * I16Vec3

Possibly .into() will work in these cases as well if the compiler can work out what type conversion you are after.

As for supporting arithmetic operations on vector masks for other vector types, I don't intend to add that for the reasons given above, that is rust itself doesn't support it.
