Struct PresentationGeneration

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

Monotonic generation of a native presentation attached to a logical window.

A generation distinguishes successive native/surface attachments for the same logical window. Public construction permits any u64; lifecycle attachment increments with checked arithmetic and never wraps.

Examples

use ailloli_ui_runtime::app::PresentationGeneration;
assert_eq!(PresentationGeneration::INITIAL.get(), 0);
assert!(PresentationGeneration::new(2) > PresentationGeneration::new(1));

Implementations

impl PresentationGeneration

Provides the operations defined for PresentationGeneration.

pub const INITIAL: Self

Initial sentinel before any native presentation has attached.

Examples

use ailloli_ui_runtime::app::PresentationGeneration;
assert_eq!(PresentationGeneration::INITIAL, PresentationGeneration::default());

pub const fn new(value: u64) -> Self

Wraps an explicit generation value without validation.

Examples

use ailloli_ui_runtime::app::PresentationGeneration;
assert_eq!(PresentationGeneration::new(u64::MAX).get(), u64::MAX);

pub const fn get(self) -> u64

Returns the underlying generation integer.

Examples

use ailloli_ui_runtime::app::PresentationGeneration;
assert_eq!(PresentationGeneration::new(7).get(), 7);
assert_eq!(PresentationGeneration::new(7).to_string(), "7");

Trait Implementations

impl Clone for PresentationGeneration

fn clone(&self) -> PresentationGeneration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PresentationGeneration

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

Formats the value using the given formatter.

impl Default for PresentationGeneration

fn default() -> PresentationGeneration

Returns the “default value” for a type.

impl Display for PresentationGeneration

Implements the fmt::Display contract for PresentationGeneration.

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

Formats the value for human-readable diagnostics.

impl Hash for PresentationGeneration

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 PresentationGeneration

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

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

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