Go分为数据类型分为值类型和引用类型,其中值类型是 int、float、string、bool、struct和array,它们直接存储值,分配栈的内存空间,它们被函数调用完之后会释放;引用类型是 slice、map、chan和值类型对应的指针 它们存储是一个地址(或者理解为指针),指针指向内存中真正存储数据的首地址,内存通常在堆分配,通过GC回收。 ...
// topbits字段,类型为[8]uint8 arr := types.NewArray(types.Types[types.TUINT8], BUCKETSIZE) field = append(field, makefield("topbits", arr)) // keys字段,类型为[8]keytype arr = types.NewArray(keytype, BUCKETSIZE) arr.SetNoalg(true) keys := makefield("keys", arr) field = app...
bucket.size } } if dirtyalloc == nil { // 根据所有桶数量创建桶数组,指针,一次性分配好普通桶+溢出桶 buckets = newarray(t.bucket, int(nbuckets)) } else { // dirtyalloc was previously generated by // the above newarray(t.bucket, int(nbuckets)) // but may not be empty. buckets ...

h.buckets,nextOverflow=makeBucketArray(t,h.B,nil)ifnextOverflow!=nil{h.extra=new(mapextra)h.extra.nextOverflow=nextOverflow}}returnh} 设计 golang的map之所以效率高,得益于下面的几处巧妙设计: (1)key hash值的后B位作为桶index查找桶 代码语言:javascript ...
makeBucketArray函数是给buckets字段分配桶空间的,知道大致功能就ok了 默认会创建2^B个bucket,如果b大于等于4,会预先创建一些溢出桶,b小于4的情况可能用不到溢出桶,没必要预先创建 2.map中赋值元素 mapassign函数,从非常宏观的角度,抛开并发安全和扩容等操作不谈,大致可以分成下面五个步骤 ...
