Example of function.
import CodeBlock from '@theme/CodeBlock'; import func from '!!raw-loader!/src/03-function/main.rs';
{func}

In the above example, ff we assign x, and y both to be 2147483647 (max
i32), the result will overflow i32 range. Unfortunately, such errors are not
caught compile time.
Check out helper methods: wrapping_add, saturating_add, overflowing_add, checked_add.

Another example where we calculate area of a circle with the input radius given by the user.
import circle_area from '!!raw-loader!/src/03-circle-area/main.rs';
{circle_area}
