(from /home/chedong/.local/share/rdoc)
------------------------------------------------------------------------
An thread-safe, write-once variation of Ruby's standard Struct. Each
member can have its value set at most once, either at construction or
any time thereafter. Attempting to assign a value to a member that has
already been set will result in a Concurrent::ImmutabilityError.
