🔬 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?
Metadata encoding version.
NB: increment this if you change the format of metadata such that
the rustc version can't be found to compare with rustc_version()
.
