Struct DdlActionRecorder 

pub struct DdlActionRecorder<'a> { /* private fields */ }

Observe-mode twin of RegisteredTableDdlGuard (private to this module) — the same authorizer, the opposite verdict. The follower MUST apply destructive DDL (its statements are the write-master’s, already committed upstream), so nothing is denied: the destructive operations are RECORDED for the post-apply bounce/purge decisions instead of being refused. One authorizer per connection: install only on paths that do not install the deny guard (protect_registered_tables = false — Cluster::exec_ddl_with_marker, in rindle-replica, is the consumer).

Implementations

impl<'a> DdlActionRecorder<'a>

pub fn install(conn: &'a Connection) -> DdlActionRecorder<'a>

pub fn mark(&self) -> (usize, usize, usize, usize)

A position marker into the observation streams, for per-statement attribution.

pub fn delta_since( &self, _: (usize, usize, usize, usize), ) -> (Vec<String>, Vec<String>, Vec<String>, Vec<String>)

The actions observed since mark — one executed statement’s attribution, in the DdlStep field order (dropped/altered tables, created/dropped indexes).

Trait Implementations

impl Drop for DdlActionRecorder<'_>

fn drop(&mut self)

Executes the destructor for this type.
