Trait ffi_utils::ReprC

pub trait ReprC {
    type C;
    type Error;
    unsafe fn clone_from_repr_c(c_repr: Self::C) -> Result<Self, Self::Error>
    where
        Self: Sized;
}

Trait to convert between FFI and Rust representations of types

Associated Types

type C

C representation of the type

type Error

Error type

Required Methods

unsafe fn clone_from_repr_c(c_repr: Self::C) -> Result<Self, Self::Error> where
    Self: Sized, 

Converts from a raw type into an owned type by cloning data
