    Resizing = 3,
    Activated = 4,

types of state on the surface

The different state values used on the surface. This is designed for state values like maximized, fullscreen. It is paired with the configure event to ensure that both the client and the compositor setting the state can be synchronized.

States set in this way are double-buffered, see wl_surface.commit.

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.

Maximized = 1

the surface is maximized

The surface is maximized. The window geometry specified in the configure event must be obeyed by the client, or the xdg_wm_base.invalid_surface_state error is raised.

The client should draw without shadow or other decoration outside of the window geometry.

Fullscreen = 2

the surface is fullscreen

The surface is fullscreen. The window geometry specified in the configure event is a maximum; the client cannot resize beyond it. For a surface to cover the whole fullscreened area, the geometry dimensions must be obeyed by the client. For more details, see xdg_toplevel.set_fullscreen.

Resizing = 3

the surface is being resized

The surface is being resized. The window geometry specified in the configure event is a maximum; the client cannot resize beyond it. Clients that have aspect ratio or cell sizing configuration can use a smaller size, however.

Activated = 4

the surface is now activated

Client window decorations should be painted as if the window is active. Do not assume this means that the window actually has keyboard or pointer focus.

TiledLeft = 5

the surface’s left edge is tiled

The window is currently in a tiled layout and the left edge is considered to be adjacent to another part of the tiling grid.

The client should draw without shadow or other decoration outside of the window geometry on the left edge.

TiledRight = 6

the surface’s right edge is tiled

The window is currently in a tiled layout and the right edge is considered to be adjacent to another part of the tiling grid.

The client should draw without shadow or other decoration outside of the window geometry on the right edge.

TiledTop = 7

the surface’s top edge is tiled

The window is currently in a tiled layout and the top edge is considered to be adjacent to another part of the tiling grid.

The client should draw without shadow or other decoration outside of the window geometry on the top edge.

TiledBottom = 8

the surface’s bottom edge is tiled

The window is currently in a tiled layout and the bottom edge is considered to be adjacent to another part of the tiling grid.

The client should draw without shadow or other decoration outside of the window geometry on the bottom edge.

Suspended = 9

surface repaint is suspended

The surface is currently not ordinarily being repainted; for example because its content is occluded by another window, or its outputs are switched off due to screen locking.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for State

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

Formats the value using the given formatter.

impl From<State> for u32

fn from(val: State) -> u32

Converts to this type from the input type.

impl Hash for State

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

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 Ord for State

fn cmp(&self, other: &State) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for State

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

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<u32> for State

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: u32) -> Result<State, ()>

Performs the conversion.

impl Copy for State

impl Eq for State

impl StructuralPartialEq for State
