[−][src]Struct pgx::callbacks::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
[src]
pub fn unregister_callback(self)
[src]
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(); }
