[−][src]Trait typic::Transparent

pub unsafe trait Transparent: Type { }

Indicates a type has no internal validity requirements.

The Transparent trait is used to indicate that a compound type does not place any additional validity restrictions on its fields.

This trait can be implemented manually:

#[typic::repr(C)]
pub struct Unconstrained {
    wizz: u8,
    bang: i8,
}

unsafe impl Transparent for Unconstrained {}

let _ : Unconstrained = u16::default().transmute_into();

Or, automatically, by marking the fields pub:

#[typic::repr(C)]
pub struct Unconstrained {
    pub wizz: u8,
    pub bang: i8,
}

let _ : Unconstrained = u16::default().transmute_into();

If the fields are marked pub, the type cannot rely on any internal validity requirements, as users of the type are free to manipulate its fields via the . operator.
