Trait ffi_utils::ReprC

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

Convert from a raw FFI type into a native Rust type by cloning the data.

Safety

The implementation of this function may be unsafe, as repr_c may be a raw pointer that needs to be valid.
