Crate fidget_shapes 

Standard library of shapes and transforms

These shapes are designed for use in higher-level languages and tools. Each shape is a single struct with named member variables. The “output” of the shape is always a Tree, and can be generated by calling Tree::from(..). Shape member variables can always be represented by variants of Value (checked by a unit test).

Every shape implements Facet + Clone + Send + Sync + Into<Tree> + 'static. When generating bindings, users are expected to inspect the shape’s type using annotations provided by the facet crate; to iterate over the entire shape library, use ShapeVisitor and visit_shapes.

For an example of binding shapes into a dynamic language, look at the implementation of fidget_rhai::shapes (specifically the internal register_shape function).
