Module deliver 

Delivering an alert to one channel, and checking a channel’s target when it is saved.

HTTP channels (Slack, Discord, webhook) are user-supplied URLs, so every request goes through the crawler’s address guard: check_url on the URL, a client whose resolver drops private and internal addresses, no redirects (a public URL that 302s to localhost is an error, never followed), no proxy, and a 10 second timeout.

Structs

GuardedHttp

The HTTP side of delivery: a client plus the address policy it was built for, so the two can’t drift apart. Build it once per process and keep it (the job context, the web settings page).

Enums

ChannelKind

ChannelTarget

Where a channel delivers to. Slack and Discord URLs carry a token, and a webhook has a secret, so Debug shows hosts only.

DeliveryError

TargetError

Functions

deliver

Delivers msg to one channel. HTTP channels check the URL with the address guard first, then post through http’s guarded client.
