Struct ComponentId 

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

Stable-within-a-run identifier for a Component.

Implementations

impl ComponentId

pub const fn new(raw: u32) -> Option<Self>

Construct from a raw 1-based index. Returns None for zero.

pub fn from_index(raw: usize) -> Self

Construct from a 0-based index (typical interner output).

Saturates at u32::MAX if raw would not fit in a u32 (i.e. on 64-bit targets at raw >= u32::MAX as usize). One slot of capacity is sacrificed at the very top; cheap.

Phase 5 module expansion may push id space toward this limit. If that becomes likely, replace this constructor with a fallible one that surfaces IdSpaceExhausted.

pub const fn get(self) -> u32

Raw 1-based id.

pub const fn index(self) -> usize

0-based index suitable for Vec lookup.

Trait Implementations

impl Clone for ComponentId

fn clone(&self) -> ComponentId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ComponentId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ComponentId

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 ComponentId

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

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

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

impl Serialize for ComponentId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
