Trait FFIConversionFrom

pub trait FFIConversionFrom<T> {
    // Required method
    unsafe fn ffi_from_const(ffi: *const Self) -> T;

    // Provided methods
    unsafe fn ffi_from(ffi: *mut Self) -> T { ... }
    unsafe fn ffi_from_opt(ffi: *mut Self) -> Option<T> { ... }
}

We pass here main context of parent program

Required Methods

unsafe fn ffi_from_const(ffi: *const Self) -> T

Safety

Provided Methods

unsafe fn ffi_from(ffi: *mut Self) -> T

Safety

unsafe fn ffi_from_opt(ffi: *mut Self) -> Option<T>

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.
