Trait MergeCombine

pub trait MergeCombine {
    // Required method
    fn merge_combine(&mut self, template: &Self);
}

Combine two map-like containers by recursively calling Merge on elements that have the same key, and adding any missing key values from the template.

Required Methods

fn merge_combine(&mut self, template: &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.
