Trait specs::saveload::MarkedBuilder

pub trait MarkedBuilder {
    fn marked<M: Marker>(self) -> Self;
}

A common trait for EntityBuilder and LazyBuilder with a marker function, allowing either to be used.

Required methods

fn marked<M: Marker>(self) -> Self

Add a Marker to the entity by fetching the associated allocator.

Examples

use specs::{
    prelude::*,
    saveload::{MarkedBuilder, SimpleMarker, SimpleMarkerAllocator},
};

struct NetworkSync;

fn mark_entity<M: Builder + MarkedBuilder>(markable: M) -> Entity {
    markable
   /* .with(Component1) */
    .marked::<SimpleMarker<NetworkSync>>()
    .build()
}

let mut world = World::new();
world.register::<SimpleMarker<NetworkSync>>();
world.insert(SimpleMarkerAllocator::<NetworkSync>::new());

mark_entity(world.create_entity());

Implementors

impl<'a> MarkedBuilder for EntityBuilder<'a>

fn marked<M>(self) -> Self where
    M: Marker, 

impl<'a> MarkedBuilder for LazyBuilder<'a>

fn marked<M>(self) -> Self where
    M: Marker, 

Add a Marker to the entity by fetching the associated allocator.

This will be applied on the next world.maintain().

Examples

use specs::{
    prelude::*,
    saveload::{MarkedBuilder, SimpleMarker, SimpleMarkerAllocator},
};

struct NetworkSync;

let mut world = World::new();
world.register::<SimpleMarker<NetworkSync>>();
world.insert(SimpleMarkerAllocator::<NetworkSync>::new());

let my_entity = lazy
    .create_entity(&entities)
    /* .with(Component1) */
    .marked::<SimpleMarker<NetworkSync>>()
    .build();

Panics

Panics during world.maintain() in case there’s no allocator added to the World.
