pub(crate) fn trim_paths_remap(
build_runner: &BuildRunner<'_, '_>,
unit: &Unit,
) -> [OsString; 3]Expand description
Computes the <from>=<to> path remap pairs for RFC 3127 trim-paths.
Order of --remap-path-prefix flags is important for -Zbuild-std.
We want to show /rustc/<hash>/library/std instead of std-0.0.0.
