# builder.WorkspaceApplyError

**Workspace Manager concept example** A working example of the core library. It can change without notice.

- **Module:** builder
- **Package:** @libtmux/workspace
- **Language:** TypeScript
- **Kind:** class
- **Source:** https://github.com/libtmux/libtmux-ts/blob/46cccfef2a546de55ce8b308249b8c76339089a0/packages/workspace/src/builder.ts#L85
- **Page:** https://libtmux.org/en/ts/latest/workspace/reference/builder-workspaceapplyerror/

Applying stopped after tmux may already have changed.

[`completed`](/en/ts/latest/workspace/reference/builder-workspaceapplyerror-completed/) records whole high-level milestones. The failed stage itself may
be partial because mutations are not transactions and transport failure may
leave delivery indeterminate. [`requiresReplan`](/en/ts/latest/workspace/reference/builder-workspaceapplyerror-requiresreplan/) asks callers to rediscover
session, window, and pane structure; it says nothing about command effects.
