Unify the concepts of successors and substitutes into a general notion
|
|
of <emphasis>equivalent expressions</emphasis>. Expressions are
|
|
equivalent if they have the same target paths with the same
|
|
identifiers. However, even though they are functionally equivalent,
|
|
they may differ stronly with respect to their <emphasis>performance
|
|
characteristics</emphasis>. For example, realising a slice is more
|
|
efficient that realising the derivation from which that slice was
|
|
produced. On the other hand, distributing sources may be more
|
|
efficient (storage- or bandwidth-wise) than distributing binaries. So
|
|
we need to be able to attach weigths or priorities or performance
|
|
annotations to expressions; Nix can then choose the most efficient
|
|
expression dependent on the context.
