Warning: numbers above are a result of guesswork. They are not 100% correct and never will be.
Flags specific for cargo-bloat
:
--crates Per crate bloatedness
--filter CRATE Filter functions by crate
--split-std Split the 'std' crate to original crates like core, alloc, etc.
--print-unknown Print methods under the '[Unknown]' tag
--full-fn Print full function name with hash values
-n NUM Number of lines to show, 0 to show all [default: 20]
-w, --wide Do not trim long function names
Correctness
The results are not perfect since function names parsing is not perfect.
Also, all non-Rust methods are skipped during crates resolving which moves jemalloc
and any other C libraries to the [Unknown]
section.
