Struct mem_query::transaction::SubUndoLog[−][src]

pub struct SubUndoLog<AccessFn, Log, SubRoot: ?Sized>(_, _, _);
Expand description

An undo log for some object that’s accessible via the main root. The AccessFn will find the object again before using the Log to revert We can’t store away a raw pointer because subsequent operations in the transaction might move the subroot (via Vec re-allocation, for example)
