remap-path-scope
The tracking issue for this feature is: #111540.
When the --remap-path-prefix
option is passed to rustc, source path prefixes in all output will be affected by default.
The --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 ofstd::file!()
macro. This is where paths in embedded panic messages come fromdiagnostics
- apply remappings to printed compiler diagnosticsdebuginfo
- apply remappings to debug informationsobject
- apply remappings to all paths in compiled executables or libraries, but not elsewhere. Currently an alias formacro,debuginfo
.all
- an alias for all of the above, also equivalent to supplying only--remap-path-prefix
without--remap-path-scope
.
Example
# This would produce an absolute path to main.rs in build outputs of
# "./main.rs".
rustc --remap-path-prefix=$(PWD)=/remapped -Zremap-path-scope=object main.rs
