Trait EncodeOptionRef

pub unsafe trait EncodeOptionRef<E: ?Sized>: EncodeOption<E> {
    // Required method
    fn encode_option_ref(
        this: Option<&Self>,
        encoder: &mut E,
        out: &mut MaybeUninit<Self::EncodedOption>,
    ) -> Result<(), EncodeError>;
}

Encodes an optional reference.

Safety

encode_option_ref must initialize all non-padding bytes of out.

Required Methods

fn encode_option_ref( this: Option<&Self>, encoder: &mut E, out: &mut MaybeUninit<Self::EncodedOption>, ) -> Result<(), EncodeError>

Encodes this optional reference into an encoder and output.

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.
