Metadata about a StorePath

Constructors

StorePathMetadata

Fields

• path :: !StorePath

  The path this metadata is about

• deriverPath :: !(Maybe StorePath)

  The path to the derivation file that built this path, if any and known.

• narHash :: !SomeNamedDigest

  The hash of the nar serialization of the path.

• references :: !StorePathSet

  The paths that this path directly references

• registrationTime :: !UTCTime

  When was this path registered valid in the store?

• narBytes :: !(Maybe Word64)

  The size of the nar serialization of the path, in bytes.

• trust :: !StorePathTrust

  How much we trust this path.

• sigs :: !(Set NarSignature)

  A set of cryptographic attestations of this path's validity.

  There is no guarantee from this type alone that these signatures are valid.

• contentAddressableAddress :: !(Maybe ContentAddressableAddress)

  Whether and how this store path is content-addressable.

  There is no guarantee from this type alone that this address is actually correct for this store path.

data StorePathTrust

How much do we trust the path, based on its provenance?

Constructors

BuiltLocally

It was built locally and thus ultimately trusted

BuiltElsewhere

It was built elsewhere (and substituted or similar) and so is less trusted
