Enum Capability

#[non_exhaustive]
#[repr(u32)]
pub enum Capability {
    ArbitraryModes = 1,
    CursorPlane = 2,
}

Available on crate feature wayland and Linux only.

capabilities advertised by the compositor

Various capabilities that can be advertised by the compositor. They are advertised one-at-a-time when the wl_fullscreen_shell interface is bound. See the wl_fullscreen_shell.capability event for more details.

ARBITRARY_MODES: This is a hint to the client that indicates that the compositor is capable of setting practically any mode on its outputs. If this capability is provided, wl_fullscreen_shell.present_surface_for_mode will almost never fail and clients should feel free to set whatever mode they like. If the compositor does not advertise this, it may still support some modes that are not advertised through wl_global.mode but it is less likely.

CURSOR_PLANE: This is a hint to the client that indicates that the compositor can handle a cursor surface from the client without actually compositing. This may be because of a hardware cursor plane or some other mechanism. If the compositor does not advertise this capability then setting wl_pointer.cursor may degrade performance or be ignored entirely. If CURSOR_PLANE is not advertised, it is recommended that the client draw its own cursor and set wl_pointer.cursor(NULL).

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.

ArbitraryModes = 1

compositor is capable of almost any output mode

CursorPlane = 2

compositor has a separate cursor plane

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capability

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

Formats the value using the given formatter.

impl Hash for Capability

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 Ord for Capability

fn cmp(&self, other: &Capability) -> 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,

Restrict a value to a certain interval.

impl PartialEq for Capability

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

impl PartialOrd for Capability

fn partial_cmp(&self, other: &Capability) -> Option<Ordering>

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 Capability

type Error = ()

The type returned in the event of a conversion error.

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

Performs the conversion.

impl Copy for Capability

impl Eq for Capability

impl StructuralPartialEq for Capability
