Struct Builder4 

Source 
pub struct Builder4<A, B, C, D = NeverPtr> { /* private fields */ }
Expand description

A builder for Union4.

An instance of this builder means that Union4 parameterized with the same type arguments are safe to construct.

Implementations§

Source§

impl<A, B, C, D> Builder4<A, B, C, D>

Source

pub const unsafe fn new_unchecked() -> Self

Assert that creating pointer unions of these types is safe.

§Safety

The pointer types must be erasable, and their alignment must meet the requirements of the target union type.
