Detailed Description

A single derived path that is built from a derivation

Built derived paths are pair of a derivation and an output name. They are evaluated by building the derivation, and then taking the resulting output path of the given output name.

Member Function Documentation

◆ getBaseStorePath()

const StorePath & nix::SingleDerivedPath::Built::getBaseStorePath ( ) const

Get the store path this is ultimately derived from (by realising and projecting outputs).

Note that this is not a property of the store object being referred to, but just of this path — how we happened to be referring to that store object. In other words, this means this function breaks "referential transparency". It should therefore be used only with great care.

◆ parse()

SingleDerivedPath::Built nix::SingleDerivedPath::Built::parse ( const StoreDirConfig & store,
ref< SingleDerivedPath > drvPath,
OutputNameView outputs,
const ExperimentalFeatureSettings & xpSettings = experimentalFeatureSettings )
static

The caller splits on the separator, so it works for both variants.

Parameters
xpSettingsStop-gap to avoid globals during unit tests.

◆ to_string()

std::string nix::SingleDerivedPath::Built::to_string ( const StoreDirConfig & store) const

Uses ^ as the separator

◆ to_string_legacy()

std::string nix::SingleDerivedPath::Built::to_string_legacy ( const StoreDirConfig & store) const

Uses ! as the separator
