Struct datazoo::enum_multimap::EnumMultimap

pub struct EnumMultimap<K: EnumSetType, V, const CLM: usize> { /* private fields */ }

A multimap stored in a JaggedArray.

The key set need to be bound and exhaustively known at compile time, ie: it must be an enum derived with #[derive(EnumSetType)].

Use it as follow: EnumMultimap<MyEnumSet, ModifyIndex, { (MyEnumSet::BIT_WIDTH - 1) as usize }>

Implementations

impl<K: EnumSetType, V, const CLM: usize> EnumMultimap<K, V, CLM>

pub fn all_rows(&self, set: EnumSet<K>) -> impl Iterator<Item = &[V]> + '_

Iterate over all rows, as slice, keyed by elements present in set.

pub fn row(&self, key: K) -> &[V]

Get row slice for key.

pub fn get(&self, direct_index: usize) -> Option<&V>

Get V at exact direct_index ignoring row sizes, acts as if the whole array was a single row.

None when direct_index is out of bound.

fn fmt(&self, f: &mut Formatter<'_>) -> Result
