Struct legion::world::Duplicate

source · [−]

pub struct Duplicate { /* private fields */ }

Expand description

A Merger which clones entities from the source world into the destination, potentially performing data transformations in the process.

Implementations

source

impl Duplicate

source

pub fn new() -> Self

Creates a new duplicate merger.

source

pub fn register_copy<T: Component + Copy>(&mut self)

Allows the merger to copy the given component into the destination world.

source

pub fn register_clone<T: Component + Clone>(&mut self)

Allows the merger to clone the given component into the destination world.

source

pub fn register_convert<Source: Component, Target: Component, F: FnMut(&Source) -> Target + 'static>(
&mut self,
convert: F
)

Allows the merger to clone the given component into the destination world with a custom clone function.

source

pub fn register_convert_raw(
 &mut self,
 src_type: ComponentTypeId,
 dst_type: ComponentTypeId,
 constructor: fn() -> Box<dyn UnknownComponentStorage>,
 duplicate_fn: Box<dyn FnMut(Range<usize>, &Archetype, &dyn UnknownComponentStorage, &mut ArchetypeWriter<'_>)>
)

Allows the merger to clone the given component into the destination world with a custom clone function.

Trait Implementations

source

impl Default for Duplicate

source

fn default() -> Duplicate

Returns the “default value” for a type. Read more

source

impl Merger for Duplicate

source

fn convert_layout(&mut self, source_layout: EntityLayout) -> EntityLayout

Calculates the destination entity layout for the given source layout.

source

fn merge_archetype(
 &mut self,
 src_entity_range: Range<usize>,
 src_arch: &Archetype,
 src_components: &Components,
 dst: &mut ArchetypeWriter<'_>
)

Merges an archetype from the source world into the destination world.

source

fn prefers_new_archetype() -> bool

Indicates if the merger prefers to merge into a new empty archetype.

source

fn entity_map(&mut self) -> EntityRewrite

Indicates how the merger wishes entity IDs to be adjusted while cloning a world.

source

fn assign_id(&mut self, existing: Entity, allocator: &mut Allocate) -> Entity

Returns the ID to use in the destination world when cloning the given entity.

source

impl<T> Downcast for T where
T: Any,

source

pub fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

source

pub fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

source

pub fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

source

pub fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more

source

impl<T> From<T> for T

const: unstable · source

pub fn from(t: T) -> T

Returns the argument unchanged.

source

impl<T, U> Into for T where
U: From<T>,

const: unstable · source

pub fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source

impl<T, U> TryFrom for T where
U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

const: unstable · source

pub fn try_from(value: U) -> Result<T, <T as TryFrom>::Error>

Performs the conversion.

source

impl<T, U> TryInto for T where
U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

pub fn try_into(self) -> Result<U, >::Error>

Performs the conversion.
