Trait IntoFFIValue

pub trait IntoFFIValue: RIType {
    // Required method
    fn into_ffi_value(
        value: Self::Inner,
        context: &mut dyn FunctionContext,
    ) -> Result<Self::FFIType>;
}

A type used as a return value in a host function. Can be turned into an FFI value.

Required Methods

fn into_ffi_value( value: Self::Inner, context: &mut dyn FunctionContext, ) -> Result<Self::FFIType>

Convert Self::Inner into an FFI value.

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.
