Struct Transaction 

pub struct Transaction {
    pub label: String,
    pub irreversible: bool,
    /* private fields */
}

A group of edits that can be reverted together.

Fields

label: String

What the edit was, for “Undid: …” messages.

irreversible: bool

Set when items were deleted for good during the transaction: their files are gone, so the edit can’t be undone and an undo history from before it no longer applies.
