Trait VariableValues

pub trait VariableValues {
    type Key: AsRef<str>;
    type Value: Value<true>;
    type Iterator<'a>: Iterator<Item = (&'a Self::Key, &'a Self::Value)>
       where Self: 'a;

    // Required method
    fn iter(&self) -> Self::Iterator<'_>;

    // Provided method
    fn get(&self, key: &str) -> Option<&Self::Value> { ... }
}

Required Associated Types

type Key: AsRef<str>

type Value: Value<true>

type Iterator<'a>: Iterator<Item = (&'a Self::Key, &'a Self::Value)> where Self: 'a

Required Methods

fn iter(&self) -> Self::Iterator<'_>

Provided Methods

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

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.

Implementations on Foreign Types
