Struct DoTransaction 

Source 
pub struct DoTransaction { /* private fields */ }
Expand description

An open transaction: the executor DoConnection::transaction hands its callback.

&DoTransaction and &mut DoTransaction are sqlx executors, like a connection’s references, and every query run through one is part of the transaction.
