Enum VirtualViewCallbackReason 

#[repr(C, u8)]
pub enum VirtualViewCallbackReason {
    InitialRender,
    DomRecreated,
    BoundsExpanded,
    EdgeScrolled(EdgeType),
    ScrollBeyondContent,
}

Reason why a VirtualView callback is being invoked.

This helps the callback optimize its behavior based on why it’s being called.

Variants

InitialRender

Initial render - first time the VirtualView appears

DomRecreated

Parent DOM was recreated (cache invalidated)

BoundsExpanded

Window/VirtualView bounds expanded beyond current scroll_size

EdgeScrolled(EdgeType)

Scroll position is near an edge (within EDGE_THRESHOLD, currently 200px)

ScrollBeyondContent

Scroll position extends beyond current scroll_size

Trait Implementations

impl Clone for VirtualViewCallbackReason

fn clone(&self) -> VirtualViewCallbackReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VirtualViewCallbackReason

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

Formats the value using the given formatter.

impl PartialEq for VirtualViewCallbackReason

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