Struct ReftableTransactionUpdate 

pub struct ReftableTransactionUpdate {
    pub refname: String,
    pub value: Option<RefValue>,
    pub log: Option<LogRecord>,
    pub expected_old: Option<ObjectId>,
}

A ref update that should be written to a reftable transaction.

The refname must already be the backend storage refname (for example a namespaced or per-worktree ref after storage routing). All updates passed to one transaction are written with the same update index, matching Git’s reftable backend for update-ref --stdin batches.

Fields

refname: String

Full storage refname to update.

value: Option<RefValue>

New ref value when this item updates a ref; None writes only a reflog line.

log: Option<LogRecord>

Optional reflog entry to record in the same table and update index.

expected_old: Option<ObjectId>

When set, the ref’s current oid must match before the update is applied (checked while the stack lock is held).
