Trait EncodeOption

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

Encodes an optional value.

Safety

encode_option must initialize all non-padding bytes of out.

Required Methods

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

Encodes this optional value 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.
