This uses stack-sizes to show the stack size (and code size) of functions. All the limitations mentioned in stack-sizes apply here.
Usage: ssize [OPTIONS]
Options:
--bin <BIN> Build only the specified binary
--example <NAME> Build only the specified example
--features <FEATURES> Space-separated list of features to activate
--all-features Activate all available features
--min-stack <MIN_STACK> Only show functions whose stack size is greater or equals to this
--out-override <OUT_OVERRIDE> Override the path of the resulting ELF - use if for some reason it's not found
-h, --help Print help
-V, --version Print version
It will build your code in release mode and show the result. e.g.
❯ ssize --example ble --features=ble --min-stack=1000
