Struct tvix_store::pathinfoservice::CachePathInfoService
source · pub struct CachePathInfoService<PS1, PS2> {
instance_name: String,
near: PS1,
far: PS2,
}
Expand description
Asks near first, if not found, asks far. If found in there, returns it, and inserts it into near. There is no negative cache. Inserts and listings are not implemented for now.

Store a PathInfo message. Implementations MUST call validate and reject
invalid messages.
source§fn list(&self) -> BoxStream<'static, Result<PathInfo, Error>>
fn list(&self) -> BoxStream<'static, Result<PathInfo, Error>>
Iterate over all PathInfo objects in the store.
Implementations can decide to disallow listing. Read more
source§fn nar_calculation_service(&self) -> Option<Box<dyn NarCalculationService>>
fn nar_calculation_service(&self) -> Option<Box<dyn NarCalculationService>>
Returns a (more) suitable NarCalculationService.
This can be used to offload NAR calculation to the remote side.
