Struct abstutil::FixedMap

source · [−]

pub struct FixedMap<K: IndexableKey, V> {
    inner: Vec<Option<V>>,
    key_type: PhantomData<K>,
}

Expand description

A drop-in replacement for BTreeMap, where the keys have the property of being array indices. Some values may be missing. Much more efficient at operations on individual objects, because it just becomes a simple array lookup.

Fields

inner: Vec<Option<V>>key_type: PhantomData<K>
