Struct ResourceKey 

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

Identity of one streamed resource: a Category and the engine’s dense index inside it (region number, texture page number, archetype number).

Packed into one u32 so a lookup is one integer compare.

Implementations

impl ResourceKey

pub const MAX_INDEX: u32

Largest index a key can carry (24 bits).

pub const fn new(category: Category, index: u32) -> Option<ResourceKey>

A key for index inside category. None when index exceeds ResourceKey::MAX_INDEX.

pub const fn category(self) -> Category

The key’s category.

pub const fn index(self) -> u32

The key’s index inside its category.

pub const fn as_u32(self) -> u32

The packed representation, stable across builds.

pub const fn from_u32(packed: u32) -> Option<ResourceKey>

Rebuild a key from ResourceKey::as_u32. None when the category bits are out of range.

Trait Implementations

impl Clone for ResourceKey

fn clone(&self) -> ResourceKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceKey

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

Formats the value using the given formatter.

impl Hash for ResourceKey

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 ResourceKey

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

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

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