in Rust, like string concatenation, are unreasonably difficult. The language demands a huge amount of fussy, obscure ritual before you can get anything done.
The contrast with Go is extreme. By four days in of exploring Go I had mastered most of the language, had a working program and tests, and was adding features to taste.
Then I found out that a feature absolutely critical for writing network servers is plain missing from Rust. Contemplate this bug report: Is there some API like "select/poll/epoll_wait"? and get a load of this answer:

ну да, у раста довольно большой порог входа, но зато потом пишешь почти как на питоне с дж**риками и без какого либо сборщика мусора
и че сложного в конкатенации строк то? [a, b].concat() ну или джоином можно.
