Type Alias VecMap1 

pub type VecMap1<K, V> = VecMap<[(K, V); 1]>;

Type alias for a VecMap with up to 1 mapping with inline storage.

This is a good default, since for usize sized keys and values, 1 mapping is the max you can fit in without making the struct larger.

Aliased Type

pub struct VecMap1<K, V>(/* private fields */);
