Macro nano_ecs::entity

macro_rules! entity {
    ($world:ident, $ind:expr, |$($n:ident: $x:ty),*| $e:expr) => { ... };
}

Accesses a single entity.

Pre-processes a mask map from component index to entity slice. This is the same for any signature, no matter which order arguments are preserved.

Warning! This is unsafe to call nested when accessing same entities more than one.
