Transaction-rs

Simple toy payment engine.

Assumptions.

Client accounts can not hold negative sums, meaning that if a previous deposit is disputed after one or more withdrawals occurred it would be possible that there aren't enough funds available. In that case the dispute is ignored and a warning is emitted.

Run:

cargo run -- example.csv > accounts.csv

Unit-tests:

cargo test

Functional-tests (inputs and outputs):

./functional_test.sh

Todo:

• add unit tests for missing transaction types
