`template struct` is a C++ syntax for defining a class or struct template. A template is a way to create a generic class or function that can be used with different types of data. When defining a template struct, the keyword `template` is followed by a set of template parameters enclosed in angle brackets, which specify the types or values that the template can be instantiated with.
For example, the following code defines a template struct `Pair` with two template parameters `T1` and `T2`, which represent the types of the first and second elements of the pair:
```
template <typename T1, typename T2>
struct Pair {
T1 first;
T2 second;
};
```
This allows us to create pairs of different types, such as `Pair<int, double>` or `Pair<std::string, bool>`. The actual types are substituted for the template parameters when the template is instantiated.
