Struct MonitorId 

#[repr(C)]
pub struct MonitorId {
    pub index: usize,
    pub hash: u64,
}

Identifies a specific monitor/display

Contains both an index (for fast current-session lookup) and a stable hash (for persistence across app restarts and monitor reconfigurations).

• index: Runtime index (0-based), may change if monitors are added/removed
• hash: Stable identifier based on monitor properties (name, size, position)

Applications can serialize hash to remember which monitor a window was on, then search for matching hash on next launch, falling back to index or PRIMARY.

Fields

index: usize

Runtime index of the monitor (may change between sessions)

hash: u64

Stable hash of monitor properties (for persistence)

Implementations

impl MonitorId

pub const PRIMARY: MonitorId

Primary/default monitor (index 0, hash 0)

pub const fn new(index: usize) -> Self

Create a MonitorId from index only (hash will be 0)

pub const fn from_index_and_hash(index: usize, hash: u64) -> Self

Create a MonitorId from index and hash

pub fn from_properties( index: usize, name: &str, position: LayoutPoint, size: LayoutSize, ) -> Self

Create a stable monitor ID from monitor properties

Uses FNV-1a hash of: name + position + size This ensures the hash is stable across app restarts as long as the monitor configuration doesn’t change significantly

Trait Implementations

impl Clone for MonitorId

fn clone(&self) -> MonitorId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MonitorId

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

Formats the value using the given formatter.

impl Hash for MonitorId

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 MonitorId

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

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

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