Struct NodeChangeSet 

pub struct NodeChangeSet {
    pub bits: u32,
}

Bit flags describing what changed about a node between old and new DOM. Multiple flags can be set simultaneously. Uses manual bit manipulation instead of bitflags crate to avoid adding a dependency.

Fields

bits: u32

Implementations

impl NodeChangeSet

pub const NODE_TYPE_CHANGED: u32 = 0b0000_0000_0000_0001

Node type changed entirely (e.g., Text → Image).

pub const TEXT_CONTENT: u32 = 0b0000_0000_0000_0010

Text content changed (for Text nodes).

pub const IDS_AND_CLASSES: u32 = 0b0000_0000_0000_0100

CSS IDs or classes changed (may cause restyle → relayout).

pub const INLINE_STYLE_LAYOUT: u32 = 0b0000_0000_0000_1000

Inline CSS properties changed that affect layout.

pub const CHILDREN_CHANGED: u32 = 0b0000_0000_0001_0000

Children added, removed, or reordered.

pub const IMAGE_CHANGED: u32 = 0b0000_0000_0010_0000

Image source changed (may affect intrinsic size).

pub const CONTENTEDITABLE: u32 = 0b0000_0000_0100_0000

Contenteditable flag changed.

pub const TAB_INDEX: u32 = 0b0000_0000_1000_0000

Tab index changed.

pub const INLINE_STYLE_PAINT: u32 = 0b0000_0001_0000_0000

Inline CSS properties changed that affect paint only.

pub const STYLED_STATE: u32 = 0b0000_0010_0000_0000

Styled node state changed (hover, active, focus, etc.).

pub const CALLBACKS: u32 = 0b0000_0100_0000_0000

Callbacks changed (new RefAny, different event handlers).

pub const DATASET: u32 = 0b0000_1000_0000_0000

Dataset changed.

pub const ACCESSIBILITY: u32 = 0b0001_0000_0000_0000

Accessibility info changed.

pub const AFFECTS_LAYOUT: u32

Any change that requires a layout pass.

pub const AFFECTS_PAINT: u32

Any change that requires a paint/display-list update (but not layout).

pub const fn empty() -> Self

pub const fn is_empty(&self) -> bool

pub const fn contains(&self, flag: u32) -> bool

pub const fn intersects(&self, mask: u32) -> bool

pub fn insert(&mut self, flag: u32)

pub const fn is_visually_unchanged(&self) -> bool

Returns true if no visual change occurred (only callbacks/dataset/a11y).

pub const fn needs_layout(&self) -> bool

Returns true if layout is needed.

pub const fn needs_paint(&self) -> bool

Returns true if paint is needed (but not necessarily layout).

Trait Implementations

impl BitOr for NodeChangeSet

type Output = NodeChangeSet

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl BitOrAssign for NodeChangeSet

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for NodeChangeSet

fn clone(&self) -> NodeChangeSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeChangeSet

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

Formats the value using the given formatter.

impl Default for NodeChangeSet

fn default() -> NodeChangeSet

Returns the “default value” for a type.

impl PartialEq for NodeChangeSet

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

impl Copy for NodeChangeSet

impl Eq for NodeChangeSet

impl StructuralPartialEq for NodeChangeSet
