Currently module is neither that complex, nor are it's outputs non-deterministic (barring srd). This can be added later on with more complex algorithms.

so far, panics where encountered when you have an addition operation that are not checked

example:

rust-coinselect/src/algorithms/lowestlarger.rs

Line 19 in 5f642a8

options.target_value + options.min_change_value + base_fees.max(options.min_absolute_fee);

It can happen if values given to options or inputs are enormous and result in overflowing u64 when making operations with them. Checking the result and returning an error like AbnormalHighAmount would be safer.

Note that in release mode, the result of the overflowing would be 0, but a returned error would still be preferred.
