Trait DictExt 

pub trait DictExt {
    // Required methods
    fn get_capability(&self, path: &impl IterablePath) -> Option<Capability>;
    fn insert_capability(
        &self,
        path: &impl IterablePath,
        capability: Capability,
    ) -> Option<Capability>;
    fn remove_capability(&self, path: &impl IterablePath) -> Option<Capability>;
}

Required Methods

fn get_capability(&self, path: &impl IterablePath) -> Option<Capability>

Returns the capability at the path, if it exists. Returns None if path is empty.

fn insert_capability( &self, path: &impl IterablePath, capability: Capability, ) -> Option<Capability>

Inserts the capability at the path. Intermediary dictionaries are created as needed. If there’s already a capability at the path, then the preexisting value is returned.

fn remove_capability(&self, path: &impl IterablePath) -> Option<Capability>

Removes the capability at the path, if it exists, and returns it.

Dyn Compatibility

This trait is not dyn compatible.

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