Information about Path

Constructors

ValidPathInfo

Fields

• path :: !Path

  Path itself

• deriverVP :: !(Maybe Path)

  The .drv which led to this Path.

• narHash :: !Text

  NAR hash

• referencesVP :: !PathSet

  The references of the Path

  Registration time should be time_t

• narSizeVP :: !Integer

  The size of the uncompressed NAR serialization of this Path.

• ultimate :: !Bool

• sigs :: ![Text]

  Signatures

• ca :: !Text

  Content-addressed Store path is computed from a cryptographic hash of the contents of the path, plus some other bits of data like the "name" part of the path.

  ‘ca’ has one of the following forms: * ‘text:sha256:hash of file contents’ (paths by makeTextPath() / addTextToStore()) * ‘fixed:r?:ht:h’ (paths by makeFixedOutputPath() / addToStore())
