Struct ApkKey 

pub struct ApkKey { /* private fields */ }

Identity of an APK for cache purposes.

A program of several archives has a key of its own (rendered results, L3, and MemoryCache go by it), and each archive its own key too: L1 and L2 files of an entry live under its archive’s key, by its name inside the archive (ApkKey::locate). Rewriting one jar of a program then costs that jar’s entries only, and a jar read alone shares them with the same jar read as part of a program.

Implementations

impl ApkKey

pub fn for_apk(apk: &Apk) -> Result<ApkKey>

Derive the key from the file size, mtime and a hash of the central directory (so a rewritten archive with the same size is not confused with the old one); for a program of several archives, from those of each and its path, in order.

pub fn as_str(&self) -> &str

pub fn locate<'n>(&self, name: &'n str) -> (&ApkKey, &'n str)

The key and name the L1 / L2 files of the entry (or logical DEX) a program calls name are stored under: its archive’s, by its name inside that archive. Other names (and a lone archive’s) stay as they are.
