CacheMode

Enum CacheMode 

Source 
pub enum CacheMode {
    Permanent,
    Cached(CacheConfig),
    Uncached,
}

Variants§

§

Permanent

Entries are pemanent, instead of a cache of the backing storage. An example is tmpfs: the DirEntry tree is the backing storage, as opposed to ext4, which uses the DirEntry tree as a cache and removes unused nodes from it.

§

Cached(CacheConfig)

Entries are cached.

§

Uncached

Entries are uncached. This can be appropriate in cases where it is difficult for the filesystem to keep the cache coherent: e.g. the /proc//task directory.
