Struct Store 

pub struct Store { /* private fields */ }

A flat, key-value store for material refractive index data.

Implementations

impl Store

pub fn new(database: HashMap<String, Material>) -> Self

pub fn get(&self, key: &str) -> Option<&Material>

Returns the item from the store associated with the given key.

Arguments

• key: The key to look up in the store.

Returns

The item associated with the given key, if it exists.

pub fn insert(&mut self, key: String, material: Material)

Inserts a new item into the store.

Arguments

• key: The key to associate with the item.
• material: The item to insert into the store.

pub fn keys(&self) -> impl Iterator<Item = &String>

Returns an iterator over the keys in the store.

pub fn retain(&mut self, predicate: impl FnMut(&String, &mut Material) -> bool)

Retains only the items in the store that satisfy the given predicate.

Arguments

• predicate: The predicate to use to retain items in the store. Any item for which the predicate returns false will be removed.

pub fn remove(&mut self, key: &str) -> Option<Material>

Removes the item associated with the given key from the store.

Arguments

• key: The key of the item to remove from the store.

pub fn remove_many(&mut self, keys: &[String])

Removes multiple items from the store.

Arguments

• keys: The keys of the items to remove from the store.
