Traits§

BuildWith
Trait implemented by EntityBuilder types.
ComponentProvider
Component provider for flat tuples.
ComponentProviderRec
Internal version of ComponentProvider that is implemented for nested tuples.
Flatten
Inverse of Nest.
GetComponent
Indicates that the implementor stores components of type T.
GetResource
Indicates that the implementor stores a resource of type T.
Nest
Trait that allows us to convert flat tuple types to nested tuple types (e.g., (A, B, C)(A, (B, (C, ())))).
PureFunctionalSystem
For systems that don’t cause side effects or need to reason about entities or components globally, it is highly recommended that you implement PureFunctionalSystem, which the library will be able to automatically parallelize.
ResourceProvider
Get the Resources struct from a world generically.
System
Trait that systems must implement.
SystemOutputTuple
Trait for converting tuples into tuples of SystemOutputs.
WorldInterface
Interface to the World struct generated via the define_world! macro.
