Finding and fixing bugs

Debugging tools are quite platform dependent. Here we will explain lldb, which is available, and macOS and other Unix-like systems.

To start debugging, you will need to compile the program with debugging symbols turned on. The normal cargo debug build is usually sufficient:

cargo build

After the program has been compiled, start the debugger:

$ sudo rust-lldb target/debug/deps/performance_polynomial3-8048e39c94dd7157

Here we reference the debugs/deps/program_name-GITHASH copy of the program. This is necessary for now just because of how lldb works.

After running lldb, you will see some information scroll past on startup. Then, you should be dropped into a LLDB Command Prompt:

(lldb) command source -s 0 '/tmp/rust-lldb-commands.YnRBkV'
Executing commands in '/tmp/rust-lldb-commands.YnRBkV'.
(lldb) command script import "/Users/andrewjohnson/.rustup/toolchains/nightly-x86_64-apple-darwin/lib/rustlib/etc/lldb_rust_formatters.py"
(lldb) type summary add --no-value --python-function...

Andrew Johnson

Andrew Johnson is a software developer who has worn many hats. Professionally, he has worked on projects written in C, C++, Java, Python, Ruby, JavaScript, Haskell, OCaml, and now Rust. Most notably, he has worked as an early employee at Topsy Labs (acquired by Apple) and FiscalNote (growing rapidly). Academically, his interests are focused on the intersection between formal language processing (such as programming languages) and existing natural language programming techniques.

Network Programming with Rust

Network Programming with Rust

Rust has steadily become one of the most important new programming languages in recent years. One the one hand, it is low-level enough to provide fine-grained control over memory while providing memory-safety through compile-time validation. Rust also guarantees data race-free parallelism. All these features make it uniquely suitable for writing low-level networking applications. This book will help developers get started on writing such applications in Rust.

Rust Essentials

Rust Essentials

Rust is the new, open source, fast and safe systems programming language for the 21st century, developed at Mozilla Research, and with a steadily growing community. It was created to solve the dilemma between high-level, slow code with minimal control over the system, and low-level, fast code with maximum system control. “Rust Essentials” will give you a head start to solve systems programming and application tasks with Rust. It is no longer necessary to learn C / C++ to develop resource intensive and low-level systems applications.

Hands-On Concurrency with Rust

Hands-On Concurrency with Rust

Writing safe and correct parallel programs is tough. Reasoning about concurrent memory modification is tough; efficiently exploiting the modern computing environment (with its multi-layered caches and deep execution pipelines) is also tough. Most systems programming languages add a further complication: unsafe memory access. The burden on you, the programmer, lies across two domains: understanding the modern machine and understanding your language's pain-points. Rust, with its safe memory model and strong type system, eases this last burden without sacrificing performance. This book will teach you to reason about program performance on modern machines and build fast, memory-safe, and concurrent software in Rust.
