Struct conrod::IndexSlot

pub struct IndexSlot {
    // some fields omitted
}

A small cache for a single unique NodeIndex.

This should be used by Widgets within their unique State for instantiating their own unique widgets.

This should reduce the need for users to directly call UiCell::new_unique_node_index and in turn reduce related mistakes (i.e. accidentally calling it and growing the graph unnecessarily).

Methods

impl IndexSlot

fn new() -> Self

Construct a new empty IndexSlot.

fn get<C>(&self, ui: &mut UiCell<C>) -> NodeIndex

Returns the NodeIndex held by the IndexSlot.

If the IndexSlot does not yet hold a NodeIndex, the UiCell will be used to produce a new_unique_node_index.

Trait Implementations

impl PartialEq for IndexSlot

fn eq(&self, __arg_0: &IndexSlot) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &IndexSlot) -> bool

This method tests for !=.

impl Debug for IndexSlot

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for IndexSlot

fn clone(&self) -> IndexSlot

Returns a copy of the value.

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

Performs copy-assignment from source.
