tour_of_rust VS concatenation_benchmarks-rs

https://tourofrust.com/ is fun. Learning rust has a weird initial learning curve dealing with the aggressive analyzer/compiler and how you have to approach your variables, but after that initial hump it is one of the coziest languages I've used. Having what was initially a bit of a nag, is now a godsend when i'm getting red-squiggles in vscode for a typo in my SQL string for a misnamed column, or a field in my template was removed and so my struct shows how it's now unused.

1. 👶 Tour of Rust is a step-by-step guide for the Rust programming language. It gives a nice overview of the language and allows the learner to also modify the code examples to experiment.

Another good learning resource is the Tour of Rust, which is more hands-on than The Book. It has a code example (which you can edit and run directly) in every section.

The bonus by learning this way is that the Rust compiler gives amazing feedback allowing you to intentionally experiment by breaking the examples. https://tourofrust.com/ was my first superficial pass.

I really liked https://tourofrust.com/ Helped me a ton.

The widely quoted string concatenation benchmarks by Hendrik Sollich are 4 years old. I added a few methods and some macros from crates.io and re-ran the benches. Here are the results: 0 ns/iter (+/- 0) from_bytes 10 ns/iter (+/- 0) concat_string_macro 10 ns/iter (+/- 0) concat_strs_macro 10 ns/iter (+/- 0) mut_string_with_capacity_push_str_char 10 ns/iter (+/- 0) string_concat_macro 10 ns/iter (+/- 1) mut_string_with_capacity_push_str 14 ns/iter (+/- 0) concat_in_place_macro 19 ns/iter (+/- 10) mut_string_with_too_much_capacity_push_str 22 ns/iter (+/- 0) array_join 24 ns/iter (+/- 0) array_concat 24 ns/iter (+/- 0) array_join_long 24 ns/iter (+/- 0) mut_string_push_str 27 ns/iter (+/- 0) string_from_plus_op 27 ns/iter (+/- 0) to_string_plus_op 29 ns/iter (+/- 0) to_owned_plus_op 30 ns/iter (+/- 0) collect_from_array_to_string 34 ns/iter (+/- 0) collect_from_vec_to_string 39 ns/iter (+/- 0) mut_string_with_too_little_capacity_push_str 43 ns/iter (+/- 1) string_from_all 52 ns/iter (+/- 0) format_macro 53 ns/iter (+/- 0) format_macro_implicit_args 68 ns/iter (+/- 1) mut_string_push_string
