This post corresponds to Chapter 9. Structs in the "Programming Rust" book.
Rust structs are data collection; fields can be named or tuple (or there can be no fields at all). Like in Go, you can have methods bound to structs (there is no separate "class" concept).
This post corresponds to "Chapter 8. Crates and Modules" in the book.
Crates are the package format for Rust; they're made up of source code plus tests, data, etc. Managing those packages is the job of cargo, came across this previously. Building crates is triggered by running cargo …
This post corresponds to "Chapter 7. Error Handling" in the book. It's a short chapter on Rusts panic and Result types.
Unlike Python, and similar to Go, Rust doesn't use Exceptions to handle errors. Instead, "expected" errors (things like EPERM or ENOENT, i.e. stuff that just can happen …
This part summarizes the sixth chapter of "Programming Rust, 2nd Edition", "Expressions".
All control structures are expressions – they can produce a value. For example:
let status =
if cpu.temperature <= MAX_TEMP {
HttpStatus::Ok
} else {
HttpStatus::ServerError // server melted
};A block can produce a …
This part summarizes the fifth chapter of "Programming Rust, 2nd Edition", "References". There was talk of references before, this chapter provides some additional detail around shared and mutable references and lifetimes.
We have encountered references previously. There are two types
r/o references, can be …
This part summarizes the fourth chapter of "Programming Rust, 2nd Edition" and deals with data ownership.
This to me is one of the most fascinating things in Rust: how it strictly tracks which part of the code holds a piece of data, and how that ownership is passed around …
Second part of my Rust learning notes, about Rust datatypes. This corresponds with chapter 3 of Programming Rust, 2nd Edition
Coming from a Python-heavy background, Rust type handling is of course completely different – everything statically typed, and a lot of nuance in basic datatypes. Fortunately the compiler …
Hello Rustlang. I have been circling around this for a while, there's lots of folks I respect that have nothing but nice things to say, and both efficiency and safety have come to the forefront more and more for me. I think the final straw was when I recently …
These are some notes and an example on hooking up Golang programs to the NATS messaging system
NATS messaging enables data sharing via a publish/subscribe mechanism across different processes, systems and platforms. NATS core offers an "at most once" quality of service. If a subscriber is …
