Module parser

This module constructs a Derivation by parsing its ATerm serialization.

Functions

from_algo_and_mode_and_digest 🔒

Consume a string containing the algo, and optionally a r: prefix, and a digest (bytes), return a CAHash::Nar or CAHash::Flat.

parse 🔒

parse_derivation

parse_input_derivations 🔒

parse_input_sources 🔒

parse_kv 🔒

Parse a list of key/value pairs into a BTreeMap. The parser for the values can be passed in. In terms of ATerm, this is just a 2-tuple, but we have the additional restriction that the first element needs to be unique across all tuples.

parse_output 🔒

Parse one output in ATerm. This is 4 string fields inside parans: output name, output path, algo (and mode), digest. Returns the output name and Output struct.

parse_outputs 🔒

Parse multiple outputs in ATerm. This is a list of things acccepted by parse_output, and takes care of turning the (String, Output) returned from it to a BTreeMap. We don’t use parse_kv here, as it’s dealing with 2-tuples, and these are 4-tuples.

parse_streaming

This parses a derivation in streaming fashion. If the parse is successful, it returns the leftover bytes which were not used for the parsing. If the parse is unsuccessful, either it returns incomplete or an error with the input as leftover.

string_to_store_path 🔒
