spaa_parse is both an executable binary that can be run, and a library that can be used in Rust programs.

Installing the `spaa_validate` executable

Assuming you have Rust/Cargo installed, run this command in a terminal:

cargo install spaa_parse

It will make the spaa_validate command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall spaa_parse uninstalls.

Adding `spaa_parse` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add spaa_parse

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

spaa_parse = "0.1.1"

The spaa_parse library will be automatically available globally. Read the spaa_parse library documentation.

Readme

spaa_parse

Parser and writer for SPAA (Stack Profile for Agentic Analysis) files.

SPAA is a structured format for representing profiling data from tools like Linux perf, DTrace, and Chrome DevTools. It's designed for analysis by both humans and LLMs.

Usage

Reading SPAA Files

use std::fs::File;
use spaa_parse::SpaaFile;

let file = File::open("profile.spaa").unwrap();
let spaa = SpaaFile::parse(file).unwrap();

println!("Source tool: {}", spaa.header.source_tool);
println!("Stacks: {}", spaa.stacks.len());

// Iterate over stacks for a specific event
for stack in spaa.stacks_for_event("cycles") {
    println!("Stack {} has {} frames", stack.id, stack.frames.len());
}

Writing SPAA Files

use std::fs::File;
use spaa_parse::{SpaaWriter, Header, Dso, Frame, Stack};

let file = File::create("output.spaa").unwrap();
let mut writer = SpaaWriter::new(file);

// Write header first, then dictionaries (DSOs, frames), then stacks
writer.write_header(&header).unwrap();
writer.write_dso(&dso).unwrap();
writer.write_frame(&frame).unwrap();
writer.write_stack(&stack).unwrap();
