BootstrapLockGuard

Struct BootstrapLockGuard 

Source
pub struct BootstrapLockGuard { /* private fields */ }
Expand description

Session-pinned advisory lock serialising concurrent bootstraps.

Only the acquiring Postgres session can release its advisory lock, so the guard pins that connection. Dropping the guard without release closes the session instead of returning it to the pool, so the lock never outlives a cancelled or panicking holder.
