Functions

build_ca_path

This builds a store path for a content-addressed path (used for fetches and FODs).

build_output_path

Builds an input-addressed store path.

build_store_path_from_fingerprint_parts 🔒

This builds a store path from fingerprint parts.

build_text_path

This builds a store path, for a CAHash::Text type store path. If you don’t want to have to pass the entire contents, you might want to use build_text_path_from_content_digest instead.

build_text_path_from_content_digest

This builds a store path, for a CAHash::Text type store path. content_digest needs to be the sha256 digest of the contents. If you have the contents as a byte slice, you can also use build_text_path.

compress_hash

compress_hash takes an arbitrarily long sequence of bytes (usually a hash digest), and returns a sequence of bytes of length OUTPUT_SIZE.

fod_digest 🔒

format_references 🔒

This contains the Nix logic to create “reference strings”, used for the output path calculation of ca paths and text paths.

hash_placeholder

Nix placeholders (i.e. values returned by builtins.placeholder) are used to populate outputs with paths that must be string-replaced with the actual placeholders later, at runtime.
