Struct SideEffectsCache 

pub struct SideEffectsCache { /* private fields */ }

Cache for package build outputs (side effects of install scripts). After a package runs its install scripts (preinstall, install, postinstall), the resulting output is cached keyed by (package, version, platform, arch).

Implementations

impl SideEffectsCache

pub fn new(base_dir: Option<PathBuf>) -> Self

Create a new SideEffectsCache, storing cached outputs under the given directory.

pub fn has(&self, package_name: &str, version: &str) -> bool

Check if side effects are cached for a given package.

pub fn store( &self, package_name: &str, version: &str, package_dir: &Path, ) -> Result<()>

Store the side effects (built output) for a package. package_dir is the directory of the installed package after scripts ran.

pub fn restore( &self, package_name: &str, version: &str, package_dir: &Path, ) -> Result<bool>

Restore cached side effects into a package directory. Returns true if side effects were restored, false if not cached.

pub fn clean(&self) -> Result<usize>

Clean all cached side effects.
