Transaction Engine

This project aims to be a Rust showcase.

Run

cargo run transactions.csv > accounts.csv

to generate the accounts CSV from standard output.

Errors will be reported to standard error (if any).

Testing

The project contains unit tests, that can be run with the usual

cargo test

In order to show how we could cache or externalize accounts data, the extended engine can be enabled with:

cargo run --features=extended transactions.csv > accounts.csv

This extended version contains a method (analyze_transaction) that could be used to stream transactions.

NB: extended engine is not unit tested, but tests can be easily ported.
