WebGo 语言运行时同时使用了多个数据结构组合表示哈希表,其中 runtime.hmap 是最核心的结构体,我们先来了解一下该结构体的内部字段: type hmap struct { count int flags uint8 B uint8 noverflow uint16 hash0 uint32 buckets unsafe.Pointer oldbuckets unsafe.Pointer nevacuate uintptr extra *mapextra } type mapextra struct { overflow *[]*bmap oldoverflow … Web// A header for a Go map. type hmap struct {count int // 代表哈希表中的元素个数, 调用len(map)时, 返回的就是该字段值. flags uint8 // 状态标志, 下文常量中会解释四种状态位含义. B uint8 // buckets(桶)的对数log_2(哈希表元素数量最大可达到装载因子*2^B) noverflow uint16 // 溢出桶的大概数量. hash0 uint32 // 哈希种子.
