Main generational allocator

Implementations

impl GenerationalAllocator

pub fn new(config: &GcConfig) -> Self

pub fn allocate( &mut self, value: Value, stats: &GcStats, ) -> Result<GcPtr<Value>>

Allocate a Value object

pub fn young_take_allocations(&mut self) -> Vec<*const u8>

Drain allocated object pointers from the young generation

pub fn young_reset(&mut self)

Reset the young generation after a collection cycle

pub fn young_mark_survivor(&mut self, ptr: *const u8)

Mark a pointer in young generation as survivor (for potential policies)

pub fn young_allocations_count(&self) -> usize

Get count of currently tracked young-generation allocations since last sweep

pub fn promote( &mut self, ptr: *const Value, _from_gen: usize, ) -> Result<GcPtr<Value>>

Promote an object to the next generation

pub fn young_has_survivors(&self) -> bool

Check if young generation currently tracks any survivors

pub fn find_generation(&self, ptr: *const u8) -> Option<usize>

Find which generation contains a pointer

pub fn young_generation_usage(&self) -> f64

Get young generation usage as a percentage

pub fn total_usage(&self) -> f64

Get total heap usage as a percentage

pub fn reconfigure(&mut self, config: &GcConfig) -> Result<()>

Reconfigure the allocator

pub fn note_survivor_and_maybe_promote(&mut self, ptr: *const u8) -> bool

Increment survival count and promote if threshold reached Increment survival count; return true if promotion occurred this cycle

pub fn logical_generation(&self, ptr: *const u8) -> Option<usize>

Query logical generation of a pointer: 0 for young, >=1 for promoted/old

pub fn clear_promotion_state(&mut self)

Clear promotion bookkeeping (e.g., after major GC)

pub fn stats(&self) -> AllocatorStats

Get allocator statistics
