}

The pointer’s shape over a piece (the .cursor() decorator, docs/cursor.md).

The named variants are the CSS cursor vocabulary: the largest set any toolkit accepts as it is (GTK and the DOM take the names verbatim), and every other toolkit’s set is a subset of it or maps onto it. A backend draws its own shape for each name, or the nearest one it has, and answers Cap::Cursor with how faithful that is. Cursor::Native reaches a shape only one toolkit names; the day::cursor::<toolkit> modules carry those as constants, gated on that toolkit’s feature, and every other backend ignores a name it does not know.

A cursor applies to the node and its descendants until a descendant sets its own. Cursor::Default hands the shape back to the platform rather than pinning an arrow, so a reactive cursor can release what it took.

Variants

Default

The platform default (an arrow), and the value that releases a node’s cursor.

Pointer

A pointing hand: links and other tap-to-activate content.

Text

An I-beam over editable or selectable text.

VerticalText

An I-beam for vertical text.

Crosshair

Move

Four-way move.

Grab

An open hand: content that can be dragged.

Grabbing

A closed hand: content being dragged.

NotAllowed

Wait

The app is busy and cannot take input.

Progress

The app is busy but still takes input.

Help

ContextMenu

Copy

A drop will copy.

Alias

A drop will link.

Cell

A table cell.

ZoomIn

ZoomOut

None

No pointer at all.

NsResize

Vertical (north–south) resize.

EwResize

Horizontal (east–west) resize.

NeswResize

Diagonal resize, north-east to south-west.

NwseResize

Diagonal resize, north-west to south-east.

ColResize

RowResize

Native(Cow<'static, str>)

A toolkit’s own named cursor, resolved by that backend’s lookup and ignored by every other. Prefer the day::cursor::<toolkit> constants, which are gated on the toolkit.

Implementations

impl Cursor

pub const NAMED: [Cursor; 25]

Every named cursor, in declaration order, what a gallery or a test walks.

pub const fn native(name: &'static str) -> Cursor

A toolkit-specific cursor by its native name (see Cursor::Native).

pub fn css_name(&self) -> &str

The CSS keyword for a named cursor, which GTK and the DOM take as it is. A native cursor answers its own name, so a backend keyed on CSS names may still recognize it.

Trait Implementations

impl Clone for Cursor

fn clone(&self) -> Cursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cursor

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

Formats the value using the given formatter.

impl Default for Cursor

fn default() -> Cursor

Returns the “default value” for a type.

impl Eq for Cursor

impl Hash for Cursor

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

where __H: Hasher,

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 for Cursor

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

Equality operator ==.

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

Inequality operator !=.
