Hash(arg) → hash

static VALUE
rb_f_hash(VALUE obj, VALUE arg)
{
    return rb_Hash(arg);
}

Converts arg to a Hash by calling arg.to_hash. Returns an empty Hash when arg is nil or [].

Example

Hash([])          #=> {}
Hash(nil)         #=> {}
Hash(key: :value) #=> {:key => :value}
Hash([1, 2, 3])   #=> TypeError
