Trait MapLike 

pub trait MapLike: Sized {
    // Required methods
    fn new() -> Self;
    fn get(&self, key: &u64) -> Option<&(NanValue, NanValue)>;
    fn insert(&self, key: u64, value: (NanValue, NanValue)) -> Self;
    fn len(&self) -> usize;
    fn iter(&self) -> impl Iterator<Item = (&u64, &(NanValue, NanValue))>;
    fn values(&self) -> impl Iterator<Item = &(NanValue, NanValue)>;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Trait abstracting the persistent-map operations needed by the arena.

Implementors provide a hash-keyed map from u64 to (NanValue, NanValue).

Required Methods

fn new() -> Self

fn get(&self, key: &u64) -> Option<&(NanValue, NanValue)>

fn insert(&self, key: u64, value: (NanValue, NanValue)) -> Self

fn len(&self) -> usize

fn iter(&self) -> impl Iterator<Item = (&u64, &(NanValue, NanValue))>

fn values(&self) -> impl Iterator<Item = &(NanValue, NanValue)>

Provided Methods

fn is_empty(&self) -> 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.
