Overview

Rescheme::from allows to copy a schema structure. This will create “fresh” inline schemas instead of inheriting/copying the original classes, making it a replication of the structure, only.

Options allow to customize the copied schema.

:exclude: ignore options from original Definition when copying.

Provided block is run per newly created Definition.

Rescheme.from(...) { |dfn| dfn[:readable] = true }
