Structs§

CompilationFiles: Collection of information about the files emitted by the compiler, and the output directory structure.
Metadata: Metadata tracks several UnitHashs, including Metadata::unit_id, Metadata::c_metadata, and Metadata::c_extra_filename.
OutputFile: Info about a single file emitted by the compiler.
UnitHash: Uniquely identify a Unit under specific circumstances, see Metadata for more.

has_remap_path_prefix 🔒: HACK: Detect the potential presence of --remap-path-prefix
hash_rustc_version 🔒: Hash the version of rustc being used during the build process.
metadata_of 🔒: Gets the metadata hash for the given Unit.
