pub trait GrpcReprScalar: GrpcRepr { }Expand description
Marker for “scalar” types — anything that can sit inside a Vec<>,
Option<>, or as the value type of a HashMap<String, V>.
Maps and lists are deliberately NOT scalars: proto3 disallows nesting
repeated repeated and map<K, map<...>>.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
