Documentation
class RecontextRebase p where Source
Some non-rebase code needs to manipulate the rebase state if one exists.
This class provides the hook for them to do so without needing to explicitly
detect that there is a rebase state: recontextRebase abstracts out that
information.
The hook is used in amend-record - look there for an explanation of how.
There is a default so that other patch types only need to declare the instance.

newtype RecontextRebase1 p Source
Check whether a given patch is a suspended rebase patch, and if so provide evidence that the start and end contexts are the same (from the point of view of the containing repo), and return a function that produces a new version with some fixups added.
Nested in a type to avoid needing an impredicative argument to Maybe.

newtype RecontextRebase2 p wY wZ Source
Return a suspended patch with the given fixups added.
Nested in a type to avoid needing an impredicative argument to a tuple.
