# String Manipulation
For string manipulation, use the util/mongoutils/str.h library.
## `str.h`
`util/mongoutils/str.h` provides string helper functions for each manipulation.
`str::stream()` is quite useful for assembling strings inline:
```
uassert(12345, str::stream() << "bad ns:" << ns, isOk);
```
## `StringData`
```
/** A StringData object wraps a 'const std::string&' or a 'const char*' without
* copying its contents. The most common usage is as a function argument that
* takes any of the two forms of strings above. Fundamentally, this class tries
* to work around the fact that string literals in C++ are char[N]'s.
*
* Important: the object StringData wraps must remain alive while the StringData
* is.
*/
class StringData {
```
