Method unrecord

atomic-repository/src/repository/history.rs:215–297

Unrecord a change from the current view. This removes the change from the view's change log without deleting the change itself. The change remains in the change store and graph, and can be re-applied later. This is similar to Gerrit's workflow where a patch can be removed from a change set, modified, and re-inserted. # Arguments `hash` - Hash of the change to unrecord `options` - Options contro
