Trait MapUtils

    // Required methods
    fn associate_to_map<K, V, F>(self, transform: F) -> HashMap<K, V>
       where F: Fn(Self::Item) -> (K, V),

Required Associated Types

type Item

Required Methods

fn associate_to_map<K, V, F>(self, transform: F) -> HashMap<K, V>

where F: Fn(Self::Item) -> (K, V), K: Eq + Hash,

fn associate_with_to_map<B, F>(self, transform: F) -> HashMap<Self::Item, B>

where F: Fn(Self::Item) -> B,

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.
