Trait ConcreteVariantArray 

pub trait ConcreteVariantArray {
    type Value: VariantValue<VariantArray = Self>;

    // Required methods
    fn is_empty(&self) -> bool;
    fn len(&self) -> usize;
    fn get(&self, index: usize) -> Option<&Self::Value>;
    fn iter(&self) -> impl Iterator<Item = &Self::Value>;
}

A trait for the concrete variant array type associated with a variant value.

Required Associated Types

type Value: VariantValue<VariantArray = Self>

The type of the value in the array.

Required Methods

fn is_empty(&self) -> bool

Whether the array is empty.

fn len(&self) -> usize

The length of the array.

fn get(&self, index: usize) -> Option<&Self::Value>

Get the value at the given index; None if the index is out of bounds.

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

An iterator over the values in the array.

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.
