Struct Cache 

pub struct Cache { /* private fields */ }

A cache for caching the results of a sizing a Grid Item or Flexbox Item

Implementations

impl Cache

pub const fn new() -> Cache

Create a new empty cache

pub fn get(&self, input: &LayoutInput) -> Option<LayoutOutput>

Try to retrieve a cached result from the cache

pub fn store(&mut self, input: &LayoutInput, layout_output: LayoutOutput)

Store a computed size in the cache

pub fn clear(&mut self) -> ClearState

Clear all cache entries and reports clear operation outcome (ClearState)

pub fn is_empty(&self) -> bool

Returns true if all cache entries are None, else false

Trait Implementations

impl Clone for Cache

fn clone(&self) -> Cache

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Cache

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

Formats the value using the given formatter.

impl Default for Cache

fn default() -> Cache

Returns the “default value” for a type.

impl PartialEq for Cache

fn eq(&self, other: &Cache) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
