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>
