Trait LazySelect

pub trait LazySelect<T>: Select<T>
where
    T: HasBoolMask<Mask = Self>,
{
    // Required method
    fn lazy_select<A, B>(self, a: A, b: B) -> T
       where A: FnOnce() -> T,
             B: FnOnce() -> T;
}

Like Select, but can avoid evaluating the input.

Required Methods

fn lazy_select<A, B>(self, a: A, b: B) -> T

where A: FnOnce() -> T, B: FnOnce() -> T,

Select lanes from the output of a when corresponding lanes in self are true, and select from the output of b when false. May avoid evaluating either option if it’s not selected.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
