Struct genesis::VecStorage [−][src]
pub struct VecStorage<T> { /* fields omitted */ }
Expand description
A storage type that stores components in a contiguous Vec
Implementations
Create a new VecStorage
Get a reference to the component associated with the given entity in self, if any.
Get a mutable reference to the component associated with the given entity in self, if any.
Set the component for the given entity. Returns Err(NoSuchEntity) if the given entity doesn’t exist. Otherwise, returns Ok(data), where data is previous data evicted by this operation (if any).
Remove the component for the given entity. Returns the previous data associated with the given entity in self. Does not check if the entity exists; only use this if you know it exists, e.g. through invariants in your code or because you retrieved this in a loop iterating over all alive entities.
Remove the component for the given entity. Returns the previous data associated with the given entity in self.
