Struct pgx::callbacks::XactCallbackReceipt

pub struct XactCallbackReceipt(_);

Registering a 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 XactCallbackReceipt

pub fn unregister_callback(self)

Consumes this XactCallbackReceipt and unregisters the registered callback it represents

Examples

use pgx::*;

let receipt = register_xact_callback(PgXactCallbackEvent::Commit, || info!("called after commit"));

let no_longer_necessary = true;

if no_longer_necessary {
    receipt.unregister_callback();
}
