Trait MaybeAsVarULE

pub trait MaybeAsVarULE {
    type EncodedStruct: ?Sized + VarULE;
}

A trait that associates a [VarULE] type with a data struct.

Some data structs can be represented compactly as a single [VarULE], such as str or a packed pattern. This trait allows for data providers to use optimizations for such types.

❗ Not all data structs benefit from this optimization. It works best when the data struct is multiplied across a large number of data marker attributes.

Both MaybeAsVarULE and MaybeEncodeAsVarULE should be implemented on all data structs. The data_struct! macro provides an impl.

Required Associated Types

type EncodedStruct: ?Sized + VarULE

The [VarULE] type for this data struct, or [()] if it cannot be represented as [VarULE].
