#to_hash ⇒ Object

Convert an Array to a Hash, providing an alternative to the native to_h() method. to_hash() is more forgiving and avoids errors. [‘a’, ‘b’, ‘c’] will become => ‘a’, 1 => ‘b’, 2 => ‘c’

#to_struct(type_class = nil) ⇒ Object

Convert an Array to a Struct. [‘a’, ‘b’, ‘c’] will become <Struct :‘0’=‘a’, :‘1’=‘b’, :‘2’=‘c’>

Parameters:

  • type_class (defaults to: nil) —

    If a sub-class of Struct is provided, this sub-class will be instantiated
