Method: JSON.fast_generate

Defined in:
lib/json/common.rb

.fast_generate(obj, opts = nil) ⇒ Object Also known as: fast_unparse

Generate a JSON document from the Ruby data structure obj and return it. This method disables the checks for circles in Ruby objects.

WARNING: Be careful not to pass any Ruby data structures with circles as obj argument because this will cause JSON to go into an infinite loop.
