Struct CacheManager

source
pub struct CacheManager<'gctx> {
    cache_root: Filesystem,
    gctx: &'gctx GlobalContext,
}
Expand description

Manages the on-disk index caches.

Fields§

§cache_root: Filesystem

The root path where caches are located.

§gctx: &'gctx GlobalContext

GlobalContext reference for convenience.

Implementations§

source§

impl<'gctx> CacheManager<'gctx>

source

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

root — The root path where caches are located.

source

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

Gets the cache associated with the key.

source

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

Associates the value with the key.

source

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