## `Field` additional arguments

When using `Field()` with Pydantic models, you can also declare additional `examples`:

			// Ignore trace logs beyond the following conditions
			for _, name := range matchingFuncNames {
				if funcName == name {
					return trace
				}

		traceLevel++
		// Read stack trace information from PC

}

// HashString - return the highway hash of the passed string
func HashString(input string) string {

We see that we are going to need some dependencies used in several places of the application.

So we put them in their own `dependencies` module (`app/dependencies.py`).

We will now use a simple dependency to read a custom `X-Token` header:
