The tracking issue for this feature is: #111540.
--remap-path-prefix option is passed to rustc, source path prefixes in all output will be affected by default.
--remap-path-scope argument can be used in conjunction with
--remap-path-prefix to determine paths in which output context should be affected.
This flag accepts a comma-separated list of values and may be specified multiple times, in which case the scopes are aggregated together. The valid scopes are:
macro- apply remappings to the expansion of
std::file!()macro. This is where paths in embedded panic messages come from
diagnostics- apply remappings to printed compiler diagnostics
unsplit-debuginfo- apply remappings to debug information only when they are written to compiled executables or libraries, but not when they are in split debuginfo files
split-debuginfo- apply remappings to debug information only when they are written to split debug information files, but not in compiled executables or libraries
split-debuginfo-path- apply remappings to the paths pointing to split debug information files. Does nothing when these files are not generated.
object- an alias for
macro,unsplit-debuginfo,split-debuginfo-path. This ensures all paths in compiled executables or libraries are remapped, but not elsewhere.
true- an alias for all of the above, also equivalent to supplying only
# This would produce an absolute path to main.rs in build outputs of # "./main.rs". rustc --remap-path-prefix=$(PWD)=/remapped -Zremap-path-prefix=object main.rs
