makemap_small:当map编译期确定初始长度不大于8,只创建hmap,不初始化buckets。 makemap64:当make函数传递的长度参数类型是int64时候,调用该函数,底层仍然是复用makemap。 makemap:初始化hash0加入随机性,计算对数B,并初始化buckets。 makemap_small源码 // makemap_small implements Go map creation for make(map[...
In themain()function, we created aCountryCodemap usingmake()function to store country code of specified country. Then we iterate map elements using range and print theKEYandVALUEof map elements on the console screen.

A map is an unordered collection of key-value pairs. It maps keys to values. The keys are unique within a map while the values may not be. The map data structure is used for fast lookups, retrieval, and deletion of data based on keys. It is one of the mo
当项目更大含有更多依赖时,代码混淆所带来的混乱会更加严重,且由于第三方依赖包也被混淆,逆向破解时就无法通过引入的第三方包来猜测代码逻辑。 总结 本文从源码实现的角度探究了 Golang 编译调用工具链的大致流程以及burrowers/garble项目,了解了如何利用 go/ast 对代码进行混淆处理。通过混淆处理,代码的逻辑结构、二进...
Finally, we create ourmap[string]interface{}, and iterate over the column names. For each column name (colName), we deference theinterface{}pointer at the current loop index from thecolumnPointersslice, which references the value in thecolumnsslice. We take this dereferenced value and store it...
