Struct cargo::core::compiler::BuildScriptOutputs

pub struct BuildScriptOutputs { /* private fields */ }

Map of packages to build script output.

This initially starts out as empty. Overridden build scripts get inserted during build_map. The rest of the entries are added immediately after each build script runs.

The Metadata is the unique metadata hash for the RunCustomBuild Unit of the package. It needs a unique key, since the build script can be run multiple times with different profiles or features. We can’t embed a Unit because this structure needs to be shareable between threads.
