Trait ExtensionOptionsFFIProvider 

pub trait ExtensionOptionsFFIProvider {
    // Required method
    fn local_or_ffi_extension<C: ConfigExtension + Clone + Default>(
        &self,
    ) -> Option<C>;
}

Required Methods

fn local_or_ffi_extension<C: ConfigExtension + Clone + Default>( &self, ) -> Option<C>

Extract a ConfigExtension. This method should attempt to first extract the extension from the local options when possible. Should that fail, it should attempt to extract the FFI options and then convert them to the desired ConfigExtension.

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.
