Trait SerializeOption

pub trait SerializeOption: Serialize {
    // Provided method
    fn serialize_option(
        this: Option<&Self>,
        parcel: &mut BorrowedParcel<'_>,
    ) -> Result<(), StatusCode> { ... }
}

Helper trait for types that can be nullable when serialized.

Provided Methods

fn serialize_option( this: Option<&Self>, parcel: &mut BorrowedParcel<'_>, ) -> Result<(), StatusCode>

Serialize an Option of this type into the given parcel.

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.
