Struct tvix_castore::directoryservice::Cache
source · pub struct Cache<DS1, DS2> {
instance_name: String,
near: DS1,
far: DS2,
}
Expand description
Asks near first, if not found, asks far. If found in there, returns it, and inserts it into near. Specifically, it always obtains the entire directory closure from far and inserts it into near, which is useful when far does not support accessing intermediate directories (but near does). There is no negative cache. Inserts and listings are not implemented for now.

Looks up a single Directory message by its digest.
The returned Directory message must be valid.
In case the directory is not found, Ok(None) is returned. Read more

'life0: 'async_trait,
Uploads a single Directory message, and returns the calculated
digest, or an error. An error must also be returned if the message is
not valid.
