Rust vs. Go: Which Side Are You On?
Notes
This is purely based on the author's personal perspective.
Adoption examples are just some instances.
It does not necessarily mean that all features are implemented in that language.
The Appeal and Adoption Examples of Go
Simple Syntax
Go has a relatively simple syntax.
If we take the difficulty level of Python or Ruby as 1,
Go is about 1.5.
It's just slightly more difficult.
Easy Concurrency
It's as simple as this.
go hoge()
Rich Libraries
The standard and ecosystem libraries are incredibly rich.
While not as extensive as Python's, it has the next best selection of libraries after Python.
Adoption Examples
- Mercari
- Google: Vitess
- and more
The Appeal and Adoption Examples of Rust
No GC
There is no GC (Garbage Collection).
Rust manages memory through its own unique methods, rather than relying on the programmer like in C or using a GC.
Speed Nearly Identical to C-family Languages
Unlike Java or Python, it is very fast because it is converted directly into machine code.
While Go is also quite fast, Rust stands a cut above the rest.
The Compiler is Incredibly Excellent
The Rust compiler is extremely strict.
This allows it to eliminate as many bugs as possible before execution.
With Rust, as long as it passes the compiler, you hardly have anything to worry about.
Adoption Examples
- Discord
- Dropbox
- and more
Both Discord and Dropbox originally wrote parts of their services in Go but migrated to Rust due to performance concerns.
So, Which One?
Go for quick implementation
Rust for pursuing performance
That's my personal take.
Since they can call each other, you can also perform gradual migrations.
