23 RateLimit only works with Twitter API v1. The rate limiting strategy of
24 Twitter API v1.1 is very different. A v1.1 compatible RateLimit role
25 may be coming, but isn't available, yet. It's interface will
26 necessarily be different.
27
29 This provides utility methods that return information about the current
30 rate limit status.
31
33 If current rate limit data is not resident, these methods will force a
34 call to "rate_limit_status". Therefore, any of these methods can throw
35 an error.
36 rate_remaining
38 Returns the number of API calls available before the next reset.
39 rate_reset
41 Returns the Unix epoch time of the next reset.
42 rate_limit
44 Returns the current hourly rate limit.
45 rate_ratio
47 Returns remaining API call limit, divided by the time remaining
48 before the next reset, as a ratio of the total rate limit per hour.
49 For example, if "rate_limit" is 150, the total rate is 150 API
51 calls per hour. If "rate_remaining" is 75, and there 1800 seconds
52 (1/2 hour) remaining before the next reset, "rate_ratio" returns
53 1.0, because there are exactly enough API calls remaining to
54 maintain he full rate of 150 calls per hour.
55 If "rate_remaining" is 30 and there are 360 seconds remaining
57 before reset, "rate_ratio" returns 2.0, because there are enough
58 API calls remaining to maintain twice the full rate of 150 calls
59 per hour.
60 As a final example, if "rate_remaining" is 15, and there are 7200
62 seconds remaining before reset, "rate_ratio" returns 0.5, because
63 there are only enough API calls remaining to maintain half the full
64 rate of 150 calls per hour.
65 until_rate($target_ratio)
67 Returns the number of seconds to wait before making another rate
68 limited API call such that $target_ratio of the full rate would be
69 available. It always returns a number greater than, or equal to
70 zero.
71 Use a target rate of 1.0 in a timeline polling loop to get a steady
73 polling rate, using all the allocated calls, and adjusted for other
74 API calls as they occur.
75 Use a target rate < 1.0 to allow a process to make calls as fast as
77 possible but not consume all of the calls available, too soon. For
78 example, if you have a process building a large social graph, you
79 may want to allow it make as many calls as possible, with no wait,
80 until 20% of the available rate remains. Use a value of 0.2 for
81 that purpose.
82 A target rate > than 1.0 can be used for a process that should only
84 use "extra" available API calls. This is useful for an application
85 that requires most of it's rate limit for normal operation.
