Structs

Remap 🔒

UnremapFile 🔒

On-disk schema of the unremap file.

Constants

CURRENT_UNREMAP_VERSION 🔒

WS_REMAP_ENV 🔒

This is an internal contract with rustc bootstrap, which needs workspace sources remapped to /rust{c,-dev}/<sha>.

Functions

append_unremap_suffix 🔒

Appends the unremap file suffix to an artifact path.

build_dir_remap 🔒

Remap all paths pointing to build.build-dir, i.e., [BUILD_DIR]/debug/deps/foo-[HASH].dwo would be remapped to /cargo/build-dir/debug/deps/foo-[HASH].dwo (note the /cargo/build-dir prefix).

git_checkout 🔒

Finds the checkout root and revision directory name of a git dependency.

join_remap 🔒

package_remap 🔒

Path prefix remap rules for dependencies.

should_emit_unremap_file 🔒

Whether an unremap file is worth emitting beside its artifacts.

sysroot_remap 🔒

Path prefix remap rules for sysroot.

trim_paths_args 🔒

Generates the --remap-path-scope and --remap-path-prefix for RFC 3127. See also the trim-paths profile option.

trim_paths_args_rustdoc 🔒

Like trim_paths_args but for rustdoc invocations.

trim_paths_remap 🔒

Computes the <from>=<to> path remap pairs for RFC 3127 trim-paths.
