Struct AdvanceableBookmark

Source
pub struct AdvanceableBookmark { /* private fields */ }
Expand description

A advanceable bookmark to satisfy the “advance-bookmarks” feature.

This is a helper for WorkspaceCommandTransaction. It provides a type-safe way to separate the work of checking whether a bookmark can be advanced and actually advancing it. Advancing the bookmark never fails, but can’t be done until the new CommitId is available. Splitting the work in this way also allows us to identify eligible bookmarks without actually moving them and return config errors to the user early.
