| # Example: Getting diagnostic through `rustc_interface` |
| |
| The [`rustc_interface`] allows you to intercept diagnostics that would |
| otherwise be printed to stderr. |
| |
| ## Getting diagnostics |
| |
| To get diagnostics from the compiler, |
| configure [`rustc_interface::Config`] to output diagnostic to a buffer, |
| and run [`TyCtxtEnsureOk::typeck`] for each item. |
| |
| ```rust |
| {{#include ../../examples/rustc-interface-getting-diagnostics.rs}} |
| ``` |
