Constructors

NarInfo

Fields

• storePath :: fp

  Absolute path of the derivation in nix store.

• url :: txt

  Relative url (to current domain) to download nar file.

• compression :: txt

  Name of the compression algorithm, eg. xz.

• fileHash :: hash

  Hash of the compressed nar file. NOTE: to compute use "nix-hash --type sha256 --flat" (srk) this isn't fixed to sha256 but a prefix indicates the type e.g.: sha256:1a6lzf... default is sha256 thought

• fileSize :: Integer

  File size of compressed nar file. NOTE: du -b

• narHash :: hash

  Hash of the decompressed nar file. NOTE: to compute use "nix-hash --type sha256 --flat --base32" (srk) this isn't fixed to sha256 but a prefix indicates the type e.g.: sha256:1a6lzf... default is sha256 thought

• narSize :: Integer

  File size of decompressed nar file. NOTE: du -b

• references :: Set fp

  Immediate dependencies of the storePath. NOTE: nix-store -q --references

• deriver :: Maybe txt

  Relative store path (to nix store root) of the deriver. NOTE: nix-store -q --deriver

• system :: Maybe txt

  System

• sig :: Maybe txt

  Signature of fields: storePath, narHash, narSize, refs.

• ca :: Maybe txt

  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.
