Rust In Peace
summary
A Rust-based billing/invoicing component at Doctolib that runs across operating systems and meets low-latency and resilience requirements by interfacing with C libraries for carte vitale and USB/Bluetooth card readers, signing and teletransmitting claims. Covers practical Rust tooling (rustup, cargo), ownership and borrowing (move, clone, Copy; passing references vs taking ownership), memory layout (stack vs heap), modules and tests, derives (Debug/Display), error handling with Result, when cloning is costly, and using C bindings instead of a garbage collector for carte vitale integration.
