Getting a Store

openStore :: IO Store

releaseStore :: Store -> IO ()

Query a path

followLinksToStorePath :: Store -> ByteString -> IO ByteString

Follow symlinks to the store and chop off the parts after the top-level store name

queryPathInfo

Arguments

:: Store

-> ByteString

Exact store path, not a subpath

-> IO (ForeignPtr (Ref ValidPathInfo))

ValidPathInfo or exception

validPathInfoNarSize :: ForeignPtr (Ref ValidPathInfo) -> Int64

The narSize field of a ValidPathInfo struct. Source: store-api.hh

validPathInfoNarHash :: ForeignPtr (Ref ValidPathInfo) -> IO ByteString

Copy the narHash field of a ValidPathInfo struct. Source: store-api.hh

validPathInfoDeriver :: ForeignPtr (Ref ValidPathInfo) -> IO ByteString

Deriver field of a ValidPathInfo struct. Source: store-api.hh

Returns unknownDeriver when missing.

unknownDeriver :: Text
