Topics

The driver

CLI wiring, and the only place that prints a diagnostic.

The driver

Frontend crates

Spans and reports, tokens, trees, and scopes.

Frontend crates

Backend crates

Desugaring, checking, three-address code, and targets.

Overview

Errors travel as Vec<Diagnostic> and only the driver renders them. Stages recover per item instead of panicking, and poisoned nodes (Ty::Error, no definition) pass through later stages silently.
