Defined in:

Overview

Evaluates a single forwarding rule against a WebhookProcessor::Result.

A rule is a Hash with three keys:

"field"    — which Result attribute to test
"operator" — how to compare
"value"    — what to compare against

Supported fields:

"event_type"  — string  ("bounce", "delivery", "complaint", …)
"source"      — string  (From: address)
"destination" — array   (To: addresses — rule passes if ANY element matches)
"subject"     — string  (email subject)

Supported operators:

"in"          — field value is included in the given array
"not_in"      — field value is NOT included in the given array
"eq"          — exact string equality
"not_eq"      — string inequality
"starts_with" — prefix match (for arrays: any element matches)
"ends_with"   — suffix match (for arrays: any element matches)
"contains"    — substring match (for arrays: any element matches)

New fields/operators can be added by extending the private methods below.
