Struct SqlInterruptScope

source
pub struct SqlInterruptScope { /* private fields */ }
Expand description

Check if an operation has been interrupted

This is used by the rust code to check if an operation should fail because it was interrupted. It handles the case where we get interrupted outside of an SQL query.
