## No Panicking
This makes extensive use of the `Result` pattern and is intended to never panic.
But unfortunately, Rust does not provide any features to prove this behavior.
The developer of this crate has not found a good solution to ensure no-panic behavior in any way.
Please report a panic immediately if you found it as issue on [github](https://github.com/ISibboI/evalexpr/issues).
Even if the crate itself is panic free, it allows the user to define custom functions that are executed by the crate.
The user needs to ensure that the function he provides to the crate never panic.
## Closing Notes
If you have any ideas for features or see any problems in the code, architecture, interface, algorithmics or documentation, please open an issue on github.
