Struct rui::ViewId

pub struct ViewId {
    pub id: u64,
}

ViewId is a unique identifier for a view. We’re using a u64 and hashing under the assumption there won’t be collisions. The underlying u64 is a function of the path down the view tree.

Fields

id: u64

Implementations

impl ViewId

pub fn child<Index: Hash>(&self, index: &Index) -> Self

Computes the ID for a child using a hashable value. For views which don’t have dynamic children (e.g. vstack etc.) the value will be the integer index of the child. Dynamic views (e.g. list) will hash an item identifier.

pub fn access_id(&self) -> NodeId

Returns the corresponding AccessKit ID. We’re assuming the underlying u64 isn’t zero.

Trait Implementations

impl Clone for ViewId

fn clone(&self) -> ViewId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ViewId

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

Formats the value using the given formatter.

impl Default for ViewId

fn default() -> ViewId

Returns the “default value” for a type.

impl Hash for ViewId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<ViewId> for ViewId

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

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

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

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