Struct Store 

pub struct Store { /* private fields */ }

A loaded cache: what the last run stored, and what this run has produced.

Implementations

impl Store

pub fn empty() -> Self

An empty store, for a run with caching disabled.

pub fn load(project_root: &Path) -> Self

Load the cache under a project root, or an empty store if there is nothing usable.

pub fn get(&self, key: &CacheKey) -> Option<&Entry>

The entry for a key, if this cache has one.

pub fn insert(&mut self, key: CacheKey, entry: Entry)

Record an entry for this run.

pub fn keys(&self) -> impl Iterator<Item = &CacheKey>

Every key held, in order.

For tooling and tests that need to reach an entry without recomputing its key.

pub fn len(&self) -> usize

How many entries are held.

pub fn is_empty(&self) -> bool

Whether anything is held.

pub fn save(&self, project_root: &Path)

Write the cache under a project root, replacing whatever was there.

Silent on failure by design: an unwritable .lanekeep directory means the next run is cold, which is not something to interrupt this run over.

pub fn path_for(project_root: &Path) -> PathBuf

Where the cache file sits for a project.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result
