What does this PR do?
Adds four VRL functions that exist in the Vector docs but were missing from the Observability Pipelines Custom Processor function reference.
Functions added:
pop(Array) — removes the last item from an arrayencrypt_ip(IP) — encrypts an IP address using AES-128 or prefix-preserving modedecrypt_ip(IP) — decrypts an IP address previously encrypted withencrypt_iphaversine(Map, new category) — calculates great-circle distance and bearing between two geographic coordinatesMotivation
Reported in WEB-7892: these functions were visible in Vector VRL docs but missing from the OP Custom Processor page.
Additional notes
haversineintroduces a new Map category (sourced fromCategory::Mapin the VRL stdlib). The category nav incustom_processor.mdhas been updated accordingly.encrypt_ip/decrypt_ipare fallible (require!suffix).popandhaversineare infallible.Review checklist
