Trait ErasedWireValue 

pub trait ErasedWireValue:

    // Required methods
    fn type_id(&self) -> WireTypeId;
    fn as_any(&self) -> &dyn Any;
}

Object-safe view over WireValue.

Codec implementations work in terms of &dyn ErasedWireValue so they can be invoked through &dyn WireCodec without becoming generic. The blanket impl below makes the conversion implicit at call sites: any &T where T: WireValue coerces to &dyn ErasedWireValue.

Required Methods

fn type_id(&self) -> WireTypeId

The wire type id of the underlying concrete value.

fn as_any(&self) -> &dyn Any

Provide an Any view so codec impls can downcast to the concrete type they registered.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
