Mojo function

is_int

is_int(t: IntTuple[origin]) -> Bool

Check if an IntTuple represents a single integer value.

This function determines whether the given IntTuple contains a single integer value rather than a nested tuple structure.

Example:

```mojo
from layout.int_tuple import is_int, IntTuple

var single_value = IntTuple(5)
var nested_tuple = IntTuple(1, 2, 3)

var result1 = is_int(single_value)  # Returns True
var result2 = is_int(nested_tuple)  # Returns False
```
.
```mojo
from layout.int_tuple import is_int, IntTuple

var single_value = IntTuple(5)
var nested_tuple = IntTuple(1, 2, 3)

var result1 = is_int(single_value)  # Returns True
var result2 = is_int(nested_tuple)  # Returns False
```
.

Args:

t (IntTuple[origin]): The IntTuple to check.

Returns:

True if the IntTuple contains a single integer value, False if it's a nested tuple.
