通用对比分析：对比任意两次 dump
锁定期间分析：通用对比的特例，额外约束 prev.locked 且 curr.unlocked

__post_init__()

visualize_heap_map.Diff.__post_init__

(

self

)

is_lock_mode()

bool visualize_heap_map.Diff.is_lock_mode

(

self

)

是否为锁定期间分析模式：相邻两个 dump，第一个 locked，第二个 unlocked

curr_only()

list[Block] visualize_heap_map.Diff.curr_only

(

self

)

curr 独有的已分配块（新增）

prev_only()

list[Block] visualize_heap_map.Diff.prev_only

(

self

)

prev 独有的已分配块（释放）

_freed_addrs()

set[int] visualize_heap_map.Diff._freed_addrs ( self )

protected

lock_new()

list[Block] visualize_heap_map.Diff.lock_new

(

self

)

lock 期间新增的块（curr_only 中 idx >= locked_idx）

lock_freed()

list[Block] visualize_heap_map.Diff.lock_freed

(

self

)

lock 期间新增且在 unlock 时释放的块

leaked()

list[Block] visualize_heap_map.Diff.leaked

(

self

)

泄漏：lock 期间新增但未在 unlock 时释放

sum_size()

int visualize_heap_map.Diff.sum_size	(		self,
		list[Block]	blocks )
