----A workspace edit represents changes to many resources managed in the workspace. The edit
----should either provide `changes` or `documentChanges`. If documentChanges are present
----they are preferred over `changes` if the client can handle versioned document edits.
----
----Since version 3.13.0 a workspace edit can contain resource operations as well. If resource
----operations are present clients need to execute the operations in the order in which they
----are provided. So a workspace edit for example can consist of the following two changes:
----(1) a create file a.txt and (2) a text document edit which insert text into file a.txt.
----
----An invalid sequence (e.g. (1) delete file a.txt and (2) insert text into file a.txt) will
----cause failure of the operation. How the client recovers from the failure is described by
----the client capability: `workspace.workspaceEdit.failureHandling`

----@field changes? table<lsp.DocumentUri, lsp.TextEdit[]>

----are either an array of `TextDocumentEdit`s to express changes to n different text documents
----where each text document edit addresses a specific version of a text document. Or it can contain
----above `TextDocumentEdit`s mixed with create, rename and delete file / folder operations.
----
----Whether a client supports versioned document edits is expressed via
----`workspace.workspaceEdit.documentChanges` client capability.

----If a client neither supports `documentChanges` nor `workspace.workspaceEdit.resourceOperations` then
----only plain `TextEdit`s using the `changes` property are supported.
