Required Methods

fn compare(&self, old: &Self, created: &HashSet<Self::I>) -> Comparison

fn create_coalesce(&mut self, other: Self) -> Option<Self>

fn create(&self, ctx: &mut Self::O)

fn delete_coalesce(&mut self, other: Self) -> Option<Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
