Trait EncodeOption

pub trait EncodeOption<E: ?Sized>: EncodableOption {
    // Required method
    fn encode_option(
        this: Option<&mut Self>,
        encoder: &mut E,
        slot: Slot<'_, Self::EncodedOption<'_>>,
    ) -> Result<(), EncodeError>;
}

Encodes an optional value.

Required Methods

fn encode_option( this: Option<&mut Self>, encoder: &mut E, slot: Slot<'_, Self::EncodedOption<'_>>, ) -> Result<(), EncodeError>

Encodes this optional value into an encoder and slot.

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.
