Struct Cache 

pub struct Cache { /* private fields */ }

Save and restore guest directories under a key.

let sbx = Sandbox::get("web")?;
let hit = sbx.cache().restore("deps-abc123", None, &["deps-".to_string()])?;
if !hit.restored {
    sbx.exec(["npm", "ci"])?;
    sbx.cache().save("/app/node_modules", "deps-abc123", Compression::Zstd, false)?;
}

Implementations

impl Cache

pub fn save( &self, path: &str, key: &str, compression: Compression, force: bool, ) -> Result<CacheEntry>

Archive the guest directory at path under key.

pub fn restore( &self, key: &str, path: Option<&str>, restore_keys: &[String], ) -> Result<RestoreResult>

Restore a stored tree.

path defaults to the directory the entry was saved from. restore_keys are prefixes tried in order when key misses; within a prefix the newest matching entry wins.
