}

A standard cursor shape, defined in crcbl_core::input so the UI can name one without depending on the shell. A standard cursor shape.

Names rather than pixels, because every platform already has themed, correctly scaled, user-configured cursors; crcbl_shell::cursor explains the rest.

Exhaustive on purpose. Every shell backend maps each shape to its own stock cursor, and a shape added later must fail to compile in each of them rather than fall to an arrow through a wildcard arm. That makes adding a shape a breaking change, which is the price.

The thing under the pointer is being dragged.

Move

Move in any direction.

ResizeNorthSouth

Resize vertically.

ResizeEastWest

Resize horizontally.

ResizeNorthEastSouthWest

Resize along the ↗↙ diagonal.

ResizeNorthWestSouthEast

Implementations

impl CursorIcon

pub const ALL: &'static [CursorIcon]

Every shape, in declaration order.

pub const fn as_css_name(self) -> &'static str

The CSS/cursor-shape-v1 keyword for this shape.

Backends map from this rather than from the variant name, because the keyword is the string X11 cursor themes and the browser both index by.

pub fn from_css_name(name: &str) -> Option<CursorIcon>

The shape a CSS cursor keyword names, matched as CSS matches keywords: ignoring ASCII case. None for a keyword with no shape here, auto and none among them, which are not shapes.
