Struct specs::saveload::U64Marker

pub struct U64Marker(_);

Basic marker implementation usable for saving and loading

Trait Implementations

impl Clone for U64Marker

fn clone(&self) -> U64Marker

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for U64Marker

type Storage = DenseVecStorage<U64Marker>

Associated storage type for this component.

impl Debug for U64Marker

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for U64Marker

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for U64Marker

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 Marker for U64Marker

type Allocator = U64MarkerAllocator

Allocator for this Marker

type Identifier = u64

Id of the marker

fn id(&self) -> u64

Get this marker internal id. The value of this method should be constant.

fn update(&mut self, new_revision: Self)

This gets called when an entity is deserialized by DeserializeComponents. It can be used to update internal data that is not used for identification.

impl MarkerAllocator<U64Marker> for U64MarkerAllocator

fn allocate(&mut self, entity: Entity, id: Option<u64>) -> U64Marker

Allocates a new marker for a given entity. If you don’t pass an id, a new unique id will be created.

fn retrieve_entity_internal(&self, id: u64) -> Option<Entity>

Get an Entity by a marker identifier. This function only accepts an id; it does not update the marker data.

fn maintain(
    &mut self,
    entities: &EntitiesRes,
    storage: &ReadStorage<'_, U64Marker>
)

Maintain internal data. Cleanup if necessary.

fn retrieve_entity(
    &mut self,
    marker: M,
    storage: &mut WriteStorage<'_, M>,
    entities: &EntitiesRes
) -> Entity

Tries to retrieve an entity by the id of the marker; if no entity has a marker with the same id, a new entity will be created and marker will be inserted for it.

fn mark<'m>(
    &mut self,
    entity: Entity,
    storage: &'m mut WriteStorage<'_, M>
) -> Option<(&'m M, bool)>

Create new unique marker M and attach it to entity. Or get old marker if this entity is already marked. If entity is dead then this will return None.

impl Ord for U64Marker

fn cmp(&self, other: &U64Marker) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<U64Marker> for U64Marker

fn eq(&self, other: &U64Marker) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<U64Marker> for U64Marker

fn partial_cmp(&self, other: &U64Marker) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for U64Marker

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

Serialize this value into the given Serde serializer.
