Trait Oneof 

pub trait Oneof:
    Clone
    + PartialEq
    + Send
    + Sync { }

Marker trait implemented by generated oneof enum types.

Each oneof in a protobuf message generates a Rust enum with one variant per field in the oneof. The field on the containing message uses Option<OneofEnum>, with None representing the unset state — there is no NotSet variant.

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.
