Module workflow 

Workflow plugin (workflow) — a faithful subset of Apache APISIX’s workflow plugin: declarative traffic rules evaluated in order, where the first matching case triggers its action.

Supported actions (of APISIX’s registrable set): return (reject with a status code) and limit-count (fixed-window rate limiting via the shared counter store).

Early-exit wiring: a request rejected by a return action has the rejection already written onto Context.response and exits through the node’s denied port; an exceeded limit-count action exits through limited. Wire both to a pass-through path (straight to client.in, or an error-handler that preserves the prepared response). A counter-backend failure while evaluating limit-count is a genuine infrastructure failure and stays on error. Requests that match no rule — or that pass the limit-count check — continue through the success port.

Structs

LimitCount 🔒

Rule 🔒

WorkflowPlugin

Evaluates ordered rules; the first rule whose case matches applies its action. Rules without a case always match. No matching rule means passthrough.

Enums

Action 🔒

Statics

INSTANCE_SEQ 🔒

Distinguishes counter namespaces between workflow node instances so two nodes with identical rules don’t share windows (APISIX isolates with a per-conf _vid).

Functions

set_quota_headers 🔒

Sets the standard X-RateLimit-* response headers (APISIX’s show_limit_quota_header behavior, always on).
