Struct llhd::table::SecondaryTable

pub struct SecondaryTable<I, V> { /* fields omitted */ }

A secondary table that associates additional information with entries in a primary table.

Implementations

impl<I, V> SecondaryTable<I, V>

pub fn new() -> Self

Create a new empty table.

impl<I: TableKey, V> SecondaryTable<I, V>

pub fn add(&mut self, key: I, value: V)

Add an entry to the table.

The user must provide the key with which the information is associated.

pub fn remove(&mut self, key: I) -> Option<V>

Remove an entry from the table.

pub fn contains(&self, key: I) -> bool

Check whether an entry exists in the table.

pub fn get(&self, key: I) -> Option<&V>

Get an entry from the table, if one exists.

pub fn get_mut(&mut self, key: I) -> Option<&mut V>

Get a mutable entry from the table, if one exists.

Trait Implementations

impl<I: Clone, V: Clone> Clone for SecondaryTable<I, V>

fn clone(&self) -> SecondaryTable<I, V>
