ReqAnthropic.RateLimit (ReqAnthropic v0.2.1)

Parsed rate-limit metadata from Anthropic API response headers.

Every response from the Anthropic API includes rate-limit headers. This struct captures the ones most useful for client-side throttling:

requests_remaining — requests left in the current window
tokens_remaining — tokens left in the current window
retry_after — seconds to wait before retrying (present on 429s)

Extracting from a response

The plugin automatically parses these headers and stashes the struct in Req.Response private data. Use ReqAnthropic.rate_limit/1 to retrieve it:

{:ok, resp} = ReqAnthropic.Client.build(opts) |> Req.post(...)
rate_limit = ReqAnthropic.rate_limit(resp)
rate_limit.requests_remaining  #=> 42
