Trait used to describe metadata field propagation

Provided Methods

fn forward_propagate_context(&mut self, _context: &Self)

Update metadata values on nested contexts generally

fn forward_propagate_entry_defaults(&mut self, _context: &Self, _kind: &Self)

Update metadata values on an entry based on the outer context and inner type data

fn backward_propagate_entry_defaults(&mut self, _context: &Self, _kind: &Self)

Update metadata values on an entry based on the outer context and inner type data

fn forward_propagate_child_defaults(&mut self, _kind: &Self)

Update metadata values on a type entry based on its child type

fn backward_propagate_child_defaults(&mut self, _kind: &Self)

Update metadata values on a type entry based on its child type

Dyn Compatibility

This trait is not dyn compatible.

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