Struct MonitorHandle

pub struct MonitorHandle { /* private fields */ }

Handle to a monitor.

Allows you to retrieve information about a given monitor and can be used in Window creation.

Platform-specific

Web: A MonitorHandle created without detailed monitor permissions. will always represent the current monitor the browser window is in instead of a specific monitor. See MonitorHandleExtWeb::is_detailed() to check.

Implementations

impl MonitorHandle

pub fn name(&self) -> Option<String>

Returns a human-readable name of the monitor.

Returns None if the monitor doesn’t exist anymore.

Platform-specific

Web: Always returns None without detailed monitor permissions.

pub fn position(&self) -> Option<PhysicalPosition<i32>>

Returns the top-left corner position of the monitor relative to the larger full screen area.

Platform-specific

Web: Always returns None without detailed monitor permissions.

pub fn scale_factor(&self) -> f64

Returns the scale factor of the underlying monitor. To map logical pixels to physical pixels and vice versa, use Window::scale_factor.

See the dpi module for more information.

Platform-specific

• X11: Can be overridden using the WINIT_X11_SCALE_FACTOR environment variable.
• Wayland: May differ from Window::scale_factor.
• Android: Always returns 1.0.
• Web: Always returns 0.0 without detailed monitor permissions.

pub fn current_video_mode(&self) -> Option<VideoModeHandle>

Returns the currently active video mode of this monitor.

pub fn video_modes(&self) -> impl Iterator<Item = VideoModeHandle>

Returns all fullscreen video modes supported by this monitor.

Trait Implementations

impl Clone for MonitorHandle

fn clone(&self) -> MonitorHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MonitorHandle

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

Formats the value using the given formatter.

impl Hash for MonitorHandle

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 MonitorHandleExtWayland for MonitorHandle

fn native_id(&self) -> u32

Returns the inner identifier of the monitor.

impl MonitorHandleExtX11 for MonitorHandle

fn native_id(&self) -> u32

Returns the inner identifier of the monitor.

impl Ord for MonitorHandle

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

fn eq(&self, other: &MonitorHandle) -> 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 MonitorHandle

fn partial_cmp(&self, other: &MonitorHandle) -> 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.
