1//! The billing service: what g1t's compute costs, charged to the workspace
2//! it ran for at what g1t pays plus 20%.
3//!
4//! One paid plan, "g1t" (see `features`): $20 a month per workspace, never
5//! per person, with $10 of usage included, deployments, and more private
6//! storage. The forge is free for everyone; compute needs the plan or a
7//! card check (see `compute` and `cards`). Before anything that costs money
8//! starts, the service that starts it reserves its estimate here; when it
9//! is done, what it cost goes on the ledger plus the margin, drawn first
10//! from what the plan includes, a trial or g1t's pools (see `credits`).
11//! Every change is a ledger entry, and a balance is always the sum of its
12//! ledger.
13//!
14//! Without a card processor configured the service says so and charges
15//! nothing, so that g1t still runs where billing has not been set up.
16//!
17//! Reached only through service bindings; see `g1t_contracts::billing` for
18//! the methods and their arguments.
