Function pgrx_pg_sys::MemoryContextIsValid

source · 
pub unsafe fn MemoryContextIsValid(context: MemoryContext) -> bool
Expand description

Returns true if memory context is tagged correctly according to Postgres.

§Safety

The caller must only attempt this on a pointer to a Node. This may clarify if the pointee is correctly-initialized [MemoryContextData].

§Implementation Note

If Postgres adds more memory context types in the future, we need to do that here too.
