pub struct HashMapStorage<T>(_);
Expand description

HashMap-based storage. Best suited for rare components.

This uses the std::collections::HashMap internally.

Trait Implementations

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

Clean the storage given a bitset with bits set for valid indices. Allows us to safely drop the storage. Read more

Tries reading the data associated with an Index. This is unsafe because the external set used to protect this storage is absent. Read more

Tries mutating the data associated with an Index. This is unsafe because the external set used to protect this storage is absent. Read more

Inserts new data for a given Index. Read more

Removes the data associated with an Index. Read more

Drops the data associated with an Index. This could be used when a more efficient implementation for it exists than remove when the data is no longer needed. Defaults to simply calling remove. Read more
