Trait FFIConversionTo

pub trait FFIConversionTo<T> {
    // Required method
    unsafe fn ffi_to_const(obj: T) -> *const Self;

    // Provided methods
    unsafe fn ffi_to(obj: T) -> *mut Self { ... }
    unsafe fn ffi_to_opt(obj: Option<T>) -> *mut Self
       where Self: Sized { ... }
}

Required Methods

unsafe fn ffi_to_const(obj: T) -> *const Self

Safety

Provided Methods

unsafe fn ffi_to(obj: T) -> *mut Self

Safety

unsafe fn ffi_to_opt(obj: Option<T>) -> *mut Self

where Self: Sized,

Safety

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.
