Payments Engine

A Simple payment engine written in Rust

Usage

• Install the rust toolchain

• Run a development version
  • cargo run transactions.csv
• Build and run for/in production
  • cargo build --release
  • ./target/release/payments transactions.csv

Tests

• No tests are included at this time - this is a simple engine and requires work to be production ready

Design Methodology

• Uses Domain Driven Design to leverage Rust's type system
  • Validates/sanitizes incoming data via the type system - see Transaction and TransactionType
• Account uses an associated function to handle field updates

TODO

• Add tests
  • Unit
  • Integration
• Remove pub from struct fields, and expose via methods
