Symbol Search

What is a debug symbol?

A debug symbol is a special marker or label programmers add to their software programs to help them understand and troubleshoot the code. Debug symbols are not human-readable, but programmers use debugging tools to interpret them and get meaningful insights.

The symbol command allows you to search and display debug symbols:

symbol <regexp> - searches for and displays symbols matching the given regular expression pattern

Usage example

Consider this Rust program:

fn print_val(val: u32) {
    println!("val is {val}");
}

fn main() {
    let mut some_val = 3;
    some_val += 1;

    print_val(1337);
}

Let's examine the symbols:
