contains?(bitset, permission)

Specs

contains?(Integer, permission()) :: Boolean

Checks for the presence of a permission in a permission bitset.

This should be preferred over using :perm in Permissions.to_list(x) because this works directly using bitwise operations, and is much more efficient then going through the permissions.

Examples

Permissions.contains?(role.permissions, :manage_roles)
