Struct ScrollElement 

pub struct ScrollElement { /* private fields */ }

Element for creating a ScrollNode.

Implementations

impl ScrollElement

pub fn new( state: ScrollState, is_vertical: bool, reverse_scrolling: bool, ) -> Self

Trait Implementations

impl Clone for ScrollElement

fn clone(&self) -> ScrollElement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollElement

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

Formats the value using the given formatter.

impl Hash for ScrollElement

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 ModifierNodeElement for ScrollElement

type Node = ScrollNode

fn create(&self) -> Self::Node

Creates a new modifier node instance for this element.

fn key(&self) -> Option<u64>

Optional key used to disambiguate multiple instances of the same element type.

fn update(&self, node: &mut Self::Node)

Brings an existing modifier node up to date with the element’s data.

fn capabilities(&self) -> NodeCapabilities

Returns the capabilities of nodes created by this element. Override this to indicate which specialized traits the node implements.

fn inspector_name(&self) -> &'static str

Human readable name surfaced to inspector tooling.

fn inspector_properties(&self, _inspector: &mut dyn FnMut(&'static str, String))

Records inspector properties for tooling.

fn always_update(&self) -> bool

Whether this element requires update to be called even if eq returns true.

impl PartialEq for ScrollElement

fn eq(&self, other: &Self) -> 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.
