Struct pgx::shmem::PgSharedMem

pub struct PgSharedMem {}

This struct contains methods to drive creation of types in shared memory

Implementations

impl PgSharedMem

pub fn pg_init_locked<T: Default + PGXSharedMemory>(lock: &PgLwLock<T>)

Must be run from PG_init, use for types which are guarded by a LWLock

pub fn pg_init_atomic<T: Atomic + Default>(_atomic: &PgAtomic<T>)

Must be run from _PG_init for atomics

pub fn shmem_init_locked<T: Default + PGXSharedMemory>(lock: &PgLwLock<T>)

Must be run from the shared memory init hook, use for types which are guarded by a LWLock

pub fn shmem_init_atomic<T: Atomic + Default>(atomic: &PgAtomic<T>)

Must be run from the shared memory init hook, use for rust atomics behind PgAtomic
