Rust for Debug Interface Access (DIA) SDK

The Microsoft Debug Interface Access Software Development Kit (DIA SDK) provides access to debug information stored in program database (.pdb) files generated by Microsoft postcompiler tools.

Start by adding windows and microsoft-dia dependencies to Cargo.toml:

[dependencies.windows]
version = "0.43.0"
features = [
    "Win32_System_Com"
]

[dependencies.microsoft-dia]
version = "0.1.0"

Make use of any DIA SDK APIs as needed.

use microsoft_dia::{nsfRegularExpression, DiaSource, IDiaDataSource, SymTagFunction};
use windows::{core::*, Win32::System::Com::{CoInitializeEx, COINIT_MULTITHREADED}};

fn main() -> windows::core::Result<()> {
    unsafe {
        CoInitializeEx(None, COINIT_MULTITHREADED)?;

        let source: IDiaDataSource = microsoft_dia::helpers::NoRegCoCreate(s!("msdia140.dll"), &DiaSource)?;
        let executable = std::env::current_exe().unwrap();
        source.loadDataForExe(&HSTRING::from(executable.as_os_str()), None, None)?;

        let session = source.openSession()?;
        let symbols = session.globalScope()?.findChildren(SymTagFunction, w!("sample_functions::*"), nsfRegularExpression.0 as u32)?;

        println!("Function symbols found in sample_functions::* ({}):", &executable.to_string_lossy());

        for i in 0..symbols.Count()? {
            println!("\t{}", symbols.Item(i as u32)?.name()?);
        }

        Ok(())
    }
}
