Struct mentat_ffi::InProgress [] [src]

pub struct InProgress<'a, 'c> { /* fields omitted */ }

Represents an in-progress, not yet committed, set of changes to the store. Call commit to commit your changes, or rollback to discard them. A transaction is held open until you do so. Your changes will be implicitly dropped along with this struct.

[src]

Choose whether to use in-memory caches for running queries.

If you only have a reference to an InProgress, you can't use the easy builder. This exists so you can make your own.
