Struct cosmic::iced::advanced::graphics::Cache

pub struct Cache<T> { /* private fields */ }

A simple cache that stores generated values to avoid recomputation.

Keeps track of the last generated value after clearing.

Implementations

impl<T> Cache<T>

pub fn new() -> Cache<T>

Creates a new empty Cache.

pub fn with_group(group: Group) -> Cache<T>

Creates a new empty Cache with the given Group.

Caches within the same group may reuse internal rendering storage.

You should generally group caches that are likely to change together.

pub fn group(&self) -> Group

Returns the Group of the Cache.

pub fn put(&self, value: T)

Puts the given value in the Cache.

Notice that, given this is a cache, a mutable reference is not necessary to call this method. You can safely update the cache in rendering code.

pub fn state(&self) -> &RefCell<State<T>>

Returns a reference cell to the internal State of the Cache.

pub fn clear(&self)

Clears the Cache.

Trait Implementations

impl<T> Debug for Cache<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for Cache<T>

fn default() -> Cache<T>

Returns the “default value” for a type.
