Function write_notes_commit 

pub fn write_notes_commit(
    repo: &Repository,
    notes_ref: &str,
    entries: &[NotesTreeEntry],
    message: &str,
) -> Result<()>

Write a new notes tree and commit, updating the notes ref.

Author and committer come from GIT_{AUTHOR,COMMITTER}_{NAME,EMAIL,DATE} and user.* config, timestamped with the repository’s wall clock. Use RepositoryNotes to pass explicit identities.

entries replace the whole notes tree. The commit’s parent and the compare-and-swap value are the tip read here, so an update made after the caller read entries but before this call is overwritten; RepositoryNotes reads and writes against one tip and rejects such races.

Errors

• Ref store errors, including a compare-and-swap failure when notes_ref moves while the commit is written.
• Object write and config load failures.
