CrateDep 🔒
Serialized metadata for a crate.
When compiling a proc-macro crate, we encode many of
the
LazyArray<T>
fields as Lazy::empty()
. This serves two purposes:A list of lazily-decoded values.
A list of lazily-decoded values, with the added capability of random access.
A value of type T referred to by its absolute position
in the metadata, and which can be decoded lazily.
RawDefId 🔒
On-disk representation of
DefId
.
This creates a type-safe way to enforce that we remap the CrateNum between the on-disk
representation and the compilation session.Enums

Metadata header which includes
METADATA_VERSION
.Metadata encoding version.
N.B., increment this if you change the format of metadata such that
the rustc version can’t be found to compare with
rustc_version()
.
