Trait GroupByOwned 

pub trait GroupByOwned {
    type Item;

    // Required method
    fn group_by_owned<F, K>(
        self,
        key_selector: F,
    ) -> HashMap<K, Vec<Self::Item>>
       where F: FnMut(&Self::Item) -> K,
             K: Hash + Eq;
}

Groups items into owned vectors keyed by a selector result.

Required Associated Types

type Item

Required Methods

fn group_by_owned<F, K>(self, key_selector: F) -> HashMap<K, Vec<Self::Item>>

where F: FnMut(&Self::Item) -> K, K: Hash + Eq,

Consumes the vector and groups its items by key_selector.

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.
