Constructs a [store derivation](../glossary.md#gloss-store-derivation) from the attribute set `args`
|
|
(c.f. [derivation](#builtins-derivation). Unlike `derivation` the produced store derivation is placed
|
|
in the store *immediately* when this builtin is called, while `derivation` may defer placing store
|
|
derivations in the store until it is proven that they are used.
|
|
|
|
It then returns a new attrset with *only* the following attributes:
|
|
|
|
- `drvPath` containing the path of the store derivation;
|
|
- For each output of the derivation (`out`, `dev`, etc): an attribute named after that output containing the output path
|
