toolchain.not_built_yet

Operation is declared but not built yet.

Area 3, Logic; not declinable; the next step is usually the agent's.

The language declares some operations that aren't built yet, such as the generated oauth.approve (area 8). Calling one is an error rather than a program that can't run:

example
type ConsentId = Uuid {}action approve_consent(consent: ConsentId) -> Unit {    oauth.approve(consent)}
text
error: `oauth.approve` isn't built yet --> main.jadpo:4:5  |4 |     oauth.approve(consent)  |     ^^^^^^^^^^^^^ declared, not built  reason: The language declares `oauth.approve`, but this compiler has nothing to run it with yet, so a program that calls it couldn't run.  next: Do without `oauth.approve` for now (agent)  rule: toolchain.not_built_yet  help: https://jadpo.dev/docs/errors/toolchain.not_built_yetcheck failed: 1 error, 1 file
