Struct accesskit::NodeClassSet

pub struct NodeClassSet(/* private fields */);

Allows nodes that have the same role, actions, and set of defined properties to share metadata. Each node has a class which is created by NodeBuilder, and when NodeBuilder::build is called, the node’s class is added to the provided instance of this struct if an identical class isn’t in that set already. Once a class is added to a class set, it currently remains in that set for the life of that set, whether or not any nodes are still using the class.

It’s not an error for different nodes in the same tree, or even subsequent versions of the same node, to be built from different class sets; it’s merely suboptimal.

Note: This struct’s Default implementation doesn’t provide access to a shared set, as one might assume; it creates a new set. For a shared set, use NodeClassSet::lock_global.

Implementations

impl NodeClassSet

pub const fn new() -> Self

pub fn lock_global() -> impl DerefMut<Target = Self>

Accesses a shared class set guarded by a mutex.

Trait Implementations

impl Clone for NodeClassSet

fn clone(&self) -> NodeClassSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for NodeClassSet

fn default() -> NodeClassSet

Returns the “default value” for a type.
