Module builder 

This module contains glue code translating from [nix_compat::derivation::Derivation] to snix_build::buildservice::BuildRequest.

Modules

export_reference_graph

structured_attrs

Contains code modifying BuildRequest to honor structuredAttrs functionality.

Constants

NIX_ENVIRONMENT_VARS 🔒

These are the environment variables that Nix sets in its sandbox for every build.

Functions

calculate_pass_as_file_env 🔒

For a given key k in a derivation environment that’s supposed to be passed as file, calculate the ${k}Path key and filepath value that it’s being replaced with while preparing the build. The filepath is /build/.attrs-${nixbase32(sha256(key)).

derivation_into_build_request 🔒

Takes a [Derivation] and turns it into a snix_build::buildservice::BuildRequest. It assumes the Derivation has been validated, and all referenced output paths are present in inputs.

get_all_inputs 🔒

Get a stream of a transitive input closure for a derivation. It’s used for input propagation into the build and nixbase32 needle propagation for build output refscanning.

handle_pass_as_file 🔒

handle passAsFile, if set. For each env $x in that list, the original env is removed, and a $xPath environment var added instead, referring to a path inside the build with the contents from the original env var.

replace_placeholders 🔒

Replace all references to placeholder outputName inside the derivation

replace_placeholders_b 🔒

Replace all references to placeholder outputName inside the derivation
