DefinitionSource

enum nixf::Definition::DefinitionSource

"Source" information so we can know where the def comes from.

Enumerator
DS_With	From with <expr>;.
DS_Let	From let ... in ...
DS_LambdaArg	From ambda arg e.g. a: a + 1.
DS_LambdaNoArg_Formal	From lambda (noarg) formal, e.g. { a }: a + 1.
DS_LambdaWithArg_Arg	From lambda (with @arg) arg, e.g. a in { foo }@a: foo + 1.
DS_LambdaWithArg_Formal	From lambda (with @arg) formal, e.g. foo in { foo }@a: foo + 1.
DS_Rec	From recursive attribute set. e.g. rec { }.
DS_Builtin	Builtin names.
DS_FlakeInjectedFormal	Formal in flake outputs injected by call-flake.nix.
