vector< char>的优点过字符串？ [英] Benefits of vector<char> over string?

问题描述

此问题与此问题有关，但不完全相同。

使用 std :: vector< char> 而不是 std :: string 保持任意二进制数据，搁置与可读性相关的问题？

ie

解决方案

是的，

code>向下< char> c>
$ b

它不能使用小缓冲区优化，但另一方面必须在<$ 期间保留迭代器，引用等c $ c> swap 操作。

请参阅： 可以 std :: vector 使用小缓冲区优化？

This question is related to, but not quite the same as, this question.

Are there any benefits to using std::vector<char> instead of std::string to hold arbitrary binary data, aside from readability-related issues?

i.e. Are there any tasks which are easier/more efficient/better to perform with a vector compared to a string?

解决方案

Yes, vector<char> indeed does have more capabilities over string.

It must not use the small buffer optimizations, but on the other hand it must preserve iterators, references, etc. during a swap operation.
