Trait PairMap

pub trait PairMap<'a, K = String, V = String>
where
    K: Eq + PartialEq + Hash + From<&'a str>,
    V: From<&'a str>,
{
    const NAME: &'static str = "key-value pair";
    const EXPECTED: &'static str = "<key>=<value>";

    // Required method
    fn map(&mut self) -> &mut HashMap<K, V>;

    // Provided methods
    fn pair(input: &'a str) -> Option<(K, V)> { ... }
    fn set(&mut self, input: &'a str) { ... }
}

Provided Associated Constants

const NAME: &'static str = "key-value pair"

const EXPECTED: &'static str = "<key>=<value>"

Required Methods

fn map(&mut self) -> &mut HashMap<K, V>

Returns HashMap in the implementation struct.

Provided Methods

fn pair(input: &'a str) -> Option<(K, V)>

Breaks string into (key, value) tuple.

fn set(&mut self, input: &'a str)

Inserts key-value pair into map.

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.
