Trait Map

pub trait Map {
    type Value: Value;

    // Required methods
    fn iter(&self) -> impl Iterator<Item = (&str, &Self::Value)>;
    fn get(&self, key: &str) -> Option<&Self::Value>;
    fn contains_key(&self, key: &str) -> bool;
}

Required Associated Types

type Value: Value

Required Methods

fn iter(&self) -> impl Iterator<Item = (&str, &Self::Value)>

fn get(&self, key: &str) -> Option<&Self::Value>

fn contains_key(&self, key: &str) -> bool

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.
