Trait MapTrait 

pub trait MapTrait {
    type Key;
    type Value;

    const KEY_IDENT: &str = "key";
    const VALUE_IDENT: &str = "value";
    const DESCRIPTION: Option<&str> = None;
}

Trait defining contract for types that can be represented as maps

Examples

Implementing for a custom collection:

use google_ai_rs::MapTrait;

struct PairList<K, V>(Vec<(K, V)>);

impl<K, V> MapTrait for PairList<K, V> {
    type Key = K;
    type Value = V;
    const KEY_IDENT: &str = "k";
    const VALUE_IDENT: &str = "v";
}

Provided Associated Constants

const KEY_IDENT: &str = "key"

const VALUE_IDENT: &str = "value"

const DESCRIPTION: Option<&str> = None

Required Associated Types

type Key

type 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

impl<K, V> MapTrait for HashMap<K, V>

type Key = K

type Value = V
