Struct PageIndex 

pub struct PageIndex {
    pub page_id: u32,
    pub row_index: u32,
}

A logical address pointing to an entity’s component data within a specific ComponentPage.

This struct is the core of the relational aspect of our ECS. It decouples an entity’s identity from the physical storage of its data by acting as a coordinate.

Fields

page_id: u32

The unique identifier of the ComponentPage that stores the component data.

row_index: u32

The index of the row within the page where this entity’s components are stored.

Trait Implementations

impl<'__de, __Context> BorrowDecode<'__de, __Context> for PageIndex

fn borrow_decode<__D: BorrowDecoder<'__de, Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given BorrowDecode.

impl Clone for PageIndex

fn clone(&self) -> PageIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PageIndex

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

Formats the value using the given formatter.

impl<__Context> Decode<__Context> for PageIndex

fn decode<__D: Decoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given Decode.

impl Encode for PageIndex

fn encode<__E: Encoder>(&self, encoder: &mut __E) -> Result<(), EncodeError>

Encode a given type.

impl Hash for PageIndex

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 PartialEq for PageIndex

fn eq(&self, other: &PageIndex) -> 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.
