# Tooltips
|
||
|
|
|
||
|
|
Besides the ones covered in this workshop, there are many more tools that make embedded development easier.
|
||
|
|
Here, we'd like to introduce you to some of these tools and encourage you to play around with them and adopt them if you find them helpful!
|
||
|
|
|
||
|
|
## `cargo-bloat`
|
||
|
|
|
||
|
|
`cargo-bloat` is a useful tool to analyze the binary size of a program. You can install it through cargo:
|
||
|
|
|
||
|
|
``` console
|
||
|
|
$ cargo install cargo-bloat
|
||
|
|
(..)
|
||
|
|
Installed package `cargo-bloat v0.10.0` (..)
|
||
|
|
```
|
||
|
|
|
||
|
|
Let's inspect our beginner course's `hello` program with it:
|
||
|
|
|
||
|
|
``` console
|
||
|
|
$ cd beginner/apps
|
||
|
|
$ cargo bloat --bin hello
|
||
|
|
File .text Size Crate Name
|
||
|
|
0.7% 13.5% 1.3KiB std <char as core::fmt::Debug>::fmt
|
||
|
|
0.5% 9.6% 928B hello hello::__cortex_m_rt_main
|
||
|
|
0.4% 8.4% 804B std core::str::slice_error_fail
|
||
|
|
0.4% 8.0% 768B std core::fmt::Formatter::pad
|
||
|
|
0.3% 6.4% 614B std core::fmt::num::<impl core::fmt::Debug for usize>::fmt
|
||
|
|
(..)
|
||
|
|
5.1% 100.0% 9.4KiB .text section size, the file size is 184.5KiB
|
||
|
|
```
|
||
|
|
|
||
|
|
This breakdowns the size of the `.text` section by function. This breakdown can be used to identify the largest functions in the program; those could then be modified to make them smaller.
