    ) -> Result<(), Error> { ... }
}

An extension trait to perform commonly used operations on edits across different ref stores.

Required methods

fn assure_one_name_has_one_edit(&self) -> Result<(), BString>

Return true if each ref name has exactly one edit across multiple ref edits

fn extend_with_splits_of_symbolic_refs(
    &mut self,
    find: impl FnMut(PartialName<'_>) -> Option<Target>,
    make_entry: impl FnMut(usize, RefEdit) -> T
) -> Result<(), Error>

Split all symbolic refs into updates for the symbolic ref as well as all their referents if the deref flag is enabled.

Note no action is performed if deref isn’t specified.

fn adjust_namespace(&mut self, namespace: Option<Namespace>)

If namespace is not None, alter all edit names by prefixing them with the given namespace. Note that symbolic reference targets will also be rewritten to point into the namespace instead.

Provided methods

fn pre_process(
    &mut self,
    find: impl FnMut(PartialName<'_>) -> Option<Target>,
    make_entry: impl FnMut(usize, RefEdit) -> T,
    namespace: impl Into<Option<Namespace>>
) -> Result<(), Error>

All processing steps in one and in the correct order.

Users call this to assure derefs are honored and duplicate checks are done.
