Shell prompt generator in Rust

Why?

I want to see how long it takes for ZSH to run Rust app that generates shell prompt compared to writing same prompt generator function in shell

Roadmap

• Write test scenario
• Write Rust generator for test scenario
• Write ZSH generator for test scenario

Rules

• Complete time of execution will be measured. So test shall look like this

# 1. Check start time with microseconds precision
# 2. Run generator and store its result as ENV string
# 3. Print execution time with microseconds precision

How to run

print -P "$(cargo run --release -- --error "$?")"
