Module syntax::diagnostics::metadata [−] [src]

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

This module contains utilities for outputting metadata for diagnostic errors.

Each set of errors is mapped to a metadata file by a name, which is currently always a crate name.
