Struct pgx::callbacks::SubXactCallbackReceipt

pub struct SubXactCallbackReceipt(_);

Registering a sub-transaction event callback returns a XactCallbackReceipt that can be used to unregister the callback if it later (within the confines of the current transaction) becomes unnecessary

Implementations

impl SubXactCallbackReceipt

pub fn unregister_callback(self)

Consumes this SubXactCallbackReceipt and unregisters the registered callback it represents

Examples

use pgx::*;

let receipt = register_subxact_callback(PgSubXactCallbackEvent::CommitSub, |my_subid, parent_subid| info!("called after commit-sub: {} {}", my_subid, parent_subid));

let no_longer_necessary = true;

if no_longer_necessary {
    receipt.unregister_callback();
}
