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".
