Typedef Documentation

Xp

using nix::Xp = ExperimentalFeature

Just because writing ExperimentalFeature::CaDerivations is way too long

Enumeration Type Documentation

ExperimentalFeature

enum struct nix::ExperimentalFeature

strong

The list of available experimental features.

Function Documentation

documentExperimentalFeatures()

JSON nix::documentExperimentalFeatures

(

)

Compute the documentation of all experimental features.

See doc/manual for how this information is used.

operator<<()

std::ostream & nix::operator<<	(	std::ostream &	str,
		const ExperimentalFeature &	feature )

Shorthand for str << showExperimentalFeature(feature).

parseExperimentalFeature()

const std::optional< ExperimentalFeature > nix::parseExperimentalFeature

(

const std::string_view &

name

)

Parse an experimental feature (enum value) from its name. Experimental feature flag names are hyphenated and do not contain spaces.

parseFeatures()

ExperimentalFeatures nix::parseFeatures

(

const std::set< std::string > &

)

Parse a set of strings to the corresponding set of experimental features, ignoring (but warning for) any unknown feature.

showExperimentalFeature()

std::string_view nix::showExperimentalFeature

(

const ExperimentalFeature

)

Show the name of an experimental feature. This is the opposite of parseExperimentalFeature().

to_json()

void nix::to_json	(	JSON &	,
		const ExperimentalFeature &	)

Semi-magic conversion to and from json. See the nlohmann/json readme for more details.
