Invoking StableMir::run() on a crate that has any compilation error was
crashing the entire process. Instead, return a `CompilerError` so the
user knows compilation did not succeed.
I believe ICE will also be converted to `CompilerError`.
I'm also adding a return value to the callback, because I think it will
be handy for users (at least it was for my current task of implementing
a tool to validate stable-mir). However, if people disagree,
I can remove that.
Tweaks and improvements on SMIR around generics_of and predicates_of
r? `@oli-obk`
This allows an API like the following ...
```rust
let trait_decls = stable_mir::all_trait_decls().iter().map(|trait_def| {
let trait_decl = stable_mir::trait_decl(trait_def);
let generics = trait_decl.generics_of();
let predicates = trait_decl.predicates_of().predicates;
```
I didn't like that much `trait_def.trait_decl()` which is it possible but adding a method to a def_id that loads up a whole trait definition looks backwards to me.
Add missing high-level stable_mir::generics_of fn
We forgot to add this function in https://github.com/rust-lang/rust/pull/115092, as we have done on https://github.com/rust-lang/rust/pull/115084 and other high level APIs.
At some point I think we should re-organize the structure of the code but this is what we have for now.
r? `@compiler-errors`
Would have assigned `@oli-obk` but he is still on vacations
Add stable for Constant in smir
Previously https://github.com/rust-lang/rust/pull/114587 we covered much of the groundwork needed to cover Const in smir, so there is no reason keep `Constant` as String.
r? `@spastorino`
Treat `StatementKind::Coverage` as completely opaque for SMIR purposes
Coverage statements in MIR are heavily tied to internal details of the coverage implementation that are likely to change, and are unlikely to be useful to third-party tools for the foreseeable future.

Make Const more useful in smir
Since https://github.com/rust-lang/rust/pull/114587 is merged, we can make use of what we built and make Const more useful by making it not `Opaque`
