Enum MemoryStatisticsOutcome 

pub enum MemoryStatisticsOutcome {
    Applied,
    AlreadyOff,
    TooLate,
}

What disable_memory_statistics_at_process_start did: SQLite either accepted the switch (and allocator statistics were on or already off) or refused it.

Exhaustive on purpose: SQLite accepts or refuses the switch, and a build has the statistics on or off, so these three are every outcome there is, and a new one would fail to compile at each exhaustive match on it (the storage doctor’s report is one) instead of falling into a wildcard arm.

Variants

Applied

This build has allocator statistics on; they are now off.

AlreadyOff

This build compiles allocator statistics off; nothing changed.

TooLate

SQLite was already in use, so it refused the switch: allocator statistics stay as built. A degrade, never a startup failure.
