Module nix_compat::nixhash

Modules

• algos 🔒
• ca_hash 🔒

Enums

• CAHash
  A Nix CAHash describes a content-addressed hash of a path.
• CAHashMode
  Representation for the supported hash modes.
• Error
  Errors related to NixHash construction.
• HashAlgo
  This are the hash algorithms supported by cppnix.
• NixHash
  NixHash represents hashes known by Nix.

Functions

• decode_digest 🔒
  Decode a plain digest depending on the hash algo specified externally. hexlower, nixbase32 and base64 encodings are supported - the encoding is inferred from the input length.
• from_algo_and_digest
  Constructs a new NixHash by specifying HashAlgo and digest. It can fail if the passed digest length doesn’t match what’s expected for the passed algo.
• from_nix_str
  Parses a Nix hash string ($algo:$digest) to a NixHash.
• from_sri_str
  Parses a Nix SRI string to a NixHash. Contrary to the SRI spec, Nix doesn’t have an understanding of passing multiple hashes (with different algos) in SRI hashes. It instead simply cuts everything off after the expected length for the specified algo, and tries to parse the rest in permissive base64 (allowing missing padding).
• from_str
  Nix allows specifying hashes in various encodings, and magically just derives the encoding. This function parses strings to a NixHash.

Type Aliases

• NixHashResult
  convenience Result type for all nixhash parsing Results.
