Struct XvcEntity

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

Describes an entity in Entity Component System-sense.

It doesn’t have any semantics except being unique for a given entity. Various types of information (components) can be attached to this entity. XvcStore uses the entity as a key for the components.

It’s possible to convert to (u64, u64) or u128 back and forth. Normally, you should use XvcEntityGenerator to create entities. It randomizes the first value to be unique and saves the last number across sessions. This changed in 0.5. See https://github.com/iesahin/xvc/issues/198

impl From<(u64, u64)> for XvcEntity

fn from(e: (u64, u64)) -> XvcEntity

Converts to this type from the input type.

impl<T, U> From<ChildEntity<T, U>> for XvcEntity

where T: Storable, U: Storable,

fn from(r1ne: ChildEntity<T, U>) -> XvcEntity

Converts to this type from the input type.

impl From<u128> for XvcEntity

fn from(e: u128) -> XvcEntity

Converts to this type from the input type.

impl Hash for XvcEntity

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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<T> Index<&XvcEntity> for XvcStore<T>

where T: Storable,

type Output = T

The returned type after indexing.

fn index( &self, entity: &XvcEntity, ) -> &<XvcStore<T> as Index<&XvcEntity>>::Output

Performs the indexing (container[index]) operation.

impl Ord for XvcEntity

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

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

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

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 XvcEntity

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for XvcEntity
