Struct CacheManager 

pub struct CacheManager<'gctx> {
    cache_root: Filesystem,
    gctx: &'gctx GlobalContext,
    has_warned: RefCell<bool>,
}

Manages the on-disk index caches.

Fields

cache_root: Filesystem

The root path where caches are located.

gctx: &'gctx GlobalContext

GlobalContext reference for convenience.

has_warned: RefCell<bool>

Keeps track of if we have sent a warning message if there was an error updating the cache. The motivation is to avoid warning spam if the cache is not writable.

Implementations

impl<'gctx> CacheManager<'gctx>

pub fn new( cache_root: Filesystem, gctx: &'gctx GlobalContext, ) -> CacheManager<'gctx>

Creates a new instance of the on-disk index cache manager.

root — The root path where caches are located.

pub fn get(&self, key: &str) -> Option<Vec<u8>>

Gets the cache associated with the key.

pub fn put(&self, key: &str, value: &[u8])

Associates the value with the key.

fn put_inner(&self, cache_path: &PathBuf, value: &[u8]) -> Result<()>

pub fn invalidate(&self, key: &str)

Invalidates the cache associated with the key.

fn cache_path(&self, key: &str) -> PathBuf

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
