Use Rust

Decision:

use Rust as the main language

Context

• What should be the main language for implementation of soapberry?

Decision drivers

• Speed of development
• Type-safety
• Expressiveness
• Tooling
• Runtime-Error proneness

Considered Alternatives

Go

• Considering Go's mark-and-sweep garbage-collection strategy and the memory intensiveness of Event-Sourcing, Go potentially can cause a considerable headache in scale.
• Go's type-system is very small and lacks many features which is neccassary for a good compile-time gurantee of correctness. To be specific, lack of sum-types means type-casting at runtime.
• Go also lacks a mature generic support which makes the anything more than the most basic generic functions to be exponentially less-readable.

Other languages

• All the languages with mark-and-sweep garbage collectors are suffering from the GC problems mentioned.
• All the languages with manual memory-management (c, c++, and even zig) are making a trade-off that I would not and need not wanted to make.

Consequences

Pros

• More correctness gurantees.
• No concerns over future memory problems.
• Very expressive and condence code.

Cons

• Finding the right abstraction takes more time.
• Compilation-time and LSP speed lacks when compared to Go.
