Module pgrx::callbacks

Provides safe wrappers around Postgres’ “Transaction” and “Sub Transaction” hook system

Structs

• 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
• 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

Enums

• PgSubXactCallbackEvent
• PgXactCallbackEvent
  Postgres Transaction (Xact) Callback Events

Functions

• register_subxact_callback
• register_xact_callback
  Register a closure to be called during one of the PgrxactCallbackEvent events. Multiple closures can be registered per event (one at a time), and they are called in the order in which they were registered.
