Struct RedbPathInfoService 

pub struct RedbPathInfoService {
    instance_name: String,
    db: Arc<Db>,
}

PathInfoService implementation using redb under the hood. redb stores all of its data in a single file with a K/V pointing from a path’s output hash to its corresponding protobuf-encoded PathInfo.

Fields

instance_name: String

db: Arc<Db>

An Arc’ed Database, read-only or writeable.

Implementations

impl RedbPathInfoService

pub async fn new( instance_name: String, config: RedbPathInfoServiceConfig, ) -> Result<Self, Error>

Constructs a new instance using the specified config.

pub fn new_temporary( instance_name: String, config: RedbPathInfoServiceConfig, ) -> Result<Self, Error>

Constructs a new instance using the in-memory backend. Sync, as there’s no real IO happening.

Trait Implementations

impl Clone for RedbPathInfoService

fn clone(&self) -> RedbPathInfoService

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PathInfoService for RedbPathInfoService

fn get<'life0, 'async_trait>( &'life0 self, digest: [u8; 20], ) -> Pin<Box<dyn Future<Output = Result<Option<PathInfo>, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Retrieve a PathInfo by the output digest.

fn put<'life0, 'async_trait>( &'life0 self, path_info: PathInfo, ) -> Pin<Box<dyn Future<Output = Result<PathInfo, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Store a PathInfo.

fn list(&self) -> BoxStream<'static, Result<PathInfo, Error>>

Iterate over all PathInfo objects in the store. Implementations can decide to disallow listing.

fn has<'life0, 'async_trait>( &'life0 self, digest: [u8; 20], ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Check if a PathInfo exists. Has a naïve default impl, but store implementations may decide to implement their own.

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.
