Struct OverlayKey 

pub struct OverlayKey(/* private fields */);

The overlay registry’s own vocabulary, re-exported from frust-core so a design system naming a band, an input class, a light-dismiss policy or a surface identity does it through this one module: an OverlaySlot’s setters take exactly these types, and a widget that cannot name them cannot configure one. An overlay owner’s identity, quoted back by every overlay event routed to it.

Implementations

impl OverlayKey

pub fn next() -> OverlayKey

Allocate a key unique on this thread. Call once when the owner is built.

pub fn value(self) -> u64

The raw integer, for map keys; allocation order is not a contract.

Trait Implementations

impl Clone for OverlayKey

fn clone(&self) -> OverlayKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OverlayKey

impl Debug for OverlayKey

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

Formats the value using the given formatter.

impl Eq for OverlayKey

impl Hash for OverlayKey

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 OverlayKey

fn cmp(&self, other: &OverlayKey) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for OverlayKey

fn eq(&self, other: &OverlayKey) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for OverlayKey

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