Struct Id 

pub struct Id {
    pub index: usize,
    pub generation: u8,
}

A fixed-size sparse collection that maintains optional values at specified indices.

SparseSlot<T> provides a fixed-capacity container where each slot can either be empty (None) or contain a value (Some(T)). Once initialized, the capacity cannot be changed. Values can only be set once in empty slots - attempting to overwrite an existing value will be ignored.

Type Parameters

• T - The type of elements stored in the collection

Characteristics

• Fixed size - Capacity is determined at creation
• Sparse storage - Slots can be empty or filled
• One-time assignment - Values can only be set once per slot
• Index-based access - Direct access to elements via indices
• Iterator support - Both immutable and mutable iteration over non-empty slots

Fields

index: usize

generation: u8

Implementations

impl Id

pub fn new(index: usize, generation: u8) -> Self

pub fn index(&self) -> usize

pub fn generation(&self) -> u8

pub fn next(&self) -> Self

Trait Implementations

impl Clone for Id

fn clone(&self) -> Id

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Id

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

Formats the value using the given formatter.

impl Display for Id

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

Formats the value using the given formatter.

impl From<((usize, u8),)> for Id

fn from(((index, generation)): ((usize, u8),)) -> Self

Converts to this type from the input type.

impl Hash for Id

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 Id

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

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

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