PrimOpImpl

using nix::PrimOpImpl = void(EvalState & state, PosIdx pos, Value ** args, Value & v)

Function that implements a primop.

Function Documentation

initLibExpr()

void nix::initLibExpr

(

)

Initialise the evaluator (including Boehm GC, if applicable).

showType()

std::string_view nix::showType	(	ValueType	type,
		bool	withArticle = true )

Returns

A string representing the type of the value v.

Parameters

withArticle

Whether to begin with an english article, e.g. "an integer" vs "integer".
