Rust Code Style Guide

Error Handling

• Use eyre with bail! for early returns
• ALWAYS add error context with wrap_err() at the callee (where error occurs), not caller
• Add context even if it feels verbose - clarity > brevity

Control Flow

• Early return pattern everywhere - fail fast
• Maximum 3 levels of nesting - refactor if deeper

• by default every cargo build recompiles EVERYTHING to do with sql...
• let's improve speed by 2 orders of magnitude
• By default make export SQLX_OFFLINE=true, i.e., in config.fish/zsh/bash
  • open RustRover from terminal rustrover . you might have to add rustrover to path. just make sure it opens with default environment SQLX_OFFLINE=true.
• whenever you change a query in the dir of crate run SQLX_OFFLINE=false cargo sqlx prepare -- --tests from CLI to update queries.
• now we will only recompile query-related stuff as needed (when we update a query)

  tmux new-session -d -s $name

  # Get the total number of items.
  total=${#items[@]}

  # Initialize a counter.
  count=1
