[][src]Constant rustc_incremental::persist::file_format::RUSTC_VERSION

const RUSTC_VERSION: Option<&'static str>
🔬 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?

A version string that hopefully is always different for compiler versions with different encodings of incremental compilation artifacts. Contains the git commit hash.
