Enum CursorIcon 

#[non_exhaustive]
pub enum CursorIcon {
    Default,
    Pointer,
    Text,
    Grab,
    Grabbing,
    ColResize,
    RowResize,
    NotAllowed,
}

The pointer-cursor vocabulary, flat-re-exported from frust-core::event (and also available through authoring::CursorIcon).

A widget asks for a shape from its own pointer handling — ctx.set_cursor(CursorIcon::Pointer) — and the desktop shell applies whatever the pass resolved; the request is per-pass and stateless, so a widget that stops asking falls back to CursorIcon::Default with nothing to clear. Lifted flat rather than left inside authoring because a design-system plugin’s public builder API can name a cursor (a Button::cursor(..) override, a disabled control asking for CursorIcon::NotAllowed) without being a widget author itself. #[non_exhaustive]: match with a wildcard arm.

Honoured on desktop only — the mobile shells never read the resolved value, so setting a cursor unconditionally is safe on every platform. The platform-neutral cursor a widget requests through EventCtx::set_cursor; only a desktop shell honours it. #[non_exhaustive]: an out-of-tree match degrades an unknown variant to CursorIcon::Default.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Default

The host arrow; what a pass in which no widget asked resolves to.

Pointer

The clickable hand.

Text

Grab

Grabbing

ColResize

RowResize

NotAllowed

A refused action: a disabled control, or a drop target rejecting the drag.
