pl/rust is its own target platform, so they provide their own standard library*. The IO stuff all panics, for example. (In Rust a panic should be used to indicate invariant failure. pl/rust catches panics and converts them to postgres errors). In Rust you'd normally be able to link c code, but calling c requires unsafe because you have to manually ensure the c code upholds any relevant Rust invariants. > But it does make me curious how comprehensive a sandbox PL/Rust is providing, beyond just forbidding unsafe. They also hook the compiler and try and detect shenanigans. It's not perfect, but it's pretty thought out. *Technically the Rust standard library builds on top of a lower-level io module, which is all you have to replace.
