Allocator invariant checker

Implementations§

Source§

impl AllocInvariantChecker

Source

pub fn verify_no_double_alloc( model: &AllocatorModel, ) -> Result<(), AllocModelError>

Verify no double allocation: allocated set has no duplicates (BTreeSet guarantees this structurally, but we verify operationally)

Source

pub fn verify_no_use_after_free( model: &AllocatorModel, frame: u64, ) -> Result<(), AllocModelError>

Verify no use-after-free: freed frame is not in allocated set

Source

pub fn verify_buddy_consistency( block: &BuddyBlock, ) -> Result<(), AllocModelError>

Verify buddy consistency: buddy pairs are properly tracked

Source

pub fn verify_frame_conservation( model: &AllocatorModel, ) -> Result<(), AllocModelError>

Verify frame conservation: allocated + free = total

Source

pub fn verify_zone_correctness( frame: u64, zone: MemoryZone, ) -> Result<(), AllocModelError>

Verify zone correctness: allocations come from the correct zone
