StalkerMap

A comprehensive Rust library for building CLI network scanner applications with robust input validation, terminal interaction, and URL parsing capabilities.

Features

For advanced users: see docs for dns::resolver::agnostic and dns::compressor::agnostic
The current release provides message construction and encoding. Decoding and message transport helpers are planned for a future release.

Currently Available

(All feature versions)

Input Sanitization & Validation - Type-safe input validation with composable filters
Interactive Terminal Interface - User-friendly CLI input with validation loops
URL Parsing - Comprehensive HTTP/HTTPS URL parsing with host validation

("Agnostic" feature)

DNS message structure - With encoder helpers (Following the RFC1035)
DNS message compressor - For hostnames (Following the RFC1035)

Work in progress

(All feature versions)

Inside the dns module file you will see a roadmap of features I might implement, subject to change
A transport layer to send the DNS messages

("std" and "tokio-dep" features)

DNS Resolver - Higher-level dns queries (planned)

Planned Features

DNS Queries - Resolve hostnames and perform DNS lookups
Port Scanning - Efficient port scanning with customizable options
Directory Enumeration - Web directory and file discovery
Report Generation - Export scan results to various formats

Feature Variants

Agnostic version
- Only parsing, encoding/decoding of DNS messages and helpers.
- No executor or transport included — user chooses their own.
- Fast to integrate, lightweight, perfect for advanced/custom usage.
Default (std) version
- Blocking TCP/UDP transport using std::net.
- Basic fully functional implementation, easy to maintain.
- Ideal for users who want simplicity and don’t need async.
- Note: Network features are not yet implemented; they require additional abstractions for ease of use and it takes time.
Tokio (async) version
- Replaces blocking transport with tokio::net for async TCP/UDP.
- Supports non-blocking behaviors inspired by RFCs (TCP fallback, EDNS, retries, etc.).
- Can include opinionated helpers to accelerate scanner development.
- Note: Network features are not yet implemented (same reason as above).

Quick Start

Add this to your Cargo.toml:

[dependencies]
stalkermap = { version = "0.1.1", features = ["std"]}
stalkermap = { version = "0.1.1", features = ["tokio-dep"]}
stalkermap = { version = "0.1.1", default-features = false, features = ["agnostic"]}

Usage Examples

Basic Input & Range Validation

use stalkermap::utils::{Terminal, Sanitize, DesiredType};

// Get validated user input with range checking
let threads = Terminal::ask(
    "Enter scan threads (1-16):",
    &[Sanitize::IsBetween(1, 16)],
);
println!("Threads: {}", threads.answer);

URL Parsing and Validation

use stalkermap::utils::UrlParser;

// Parse and validate URLs
match UrlParser::new("https://example.com:8080/api") {
    Ok(url) => {
        println!("Scheme: {}", url.scheme);
        println!("Target: {}", url.target);
        println!("Port: {}", url.port);
        println!("Path: {}", url.subdirectory);
    }
    Err(e) => eprintln!("Invalid URL: {}", e),
}

Complex Input Validation

use stalkermap::utils::{Terminal, Sanitize, DesiredType};

// Multiple validation rules
let choice = Terminal::ask(
    "Choose scan type (quick/deep/custom):",
    &[
        Sanitize::IsType(DesiredType::String),
        Sanitize::MatchStrings(vec![
            "quick".to_string(),
            "deep".to_string(),
            "custom".to_string(),
        ]),
    ],
);

Complete Interactive URL Input Example

This example demonstrates the complete workflow of getting user input, validating it, and parsing URLs - perfect for network scanner applications:

use stalkermap::utils::{Terminal, Sanitize, DesiredType, UrlParser};

fn main() {
    // Get URL from user with validation
    let url: UrlParser = loop {
        let input = Terminal::ask(
            "Enter a URL (http:// or https://):",
            &[Sanitize::IsType(DesiredType::String)],
        );

        // Parse and validate the URL
        match UrlParser::new(&input.answer) {
            Ok(url) => break url,
            Err(e) => println!("{}", e)
        }
    };

    println!("Full url: {}", url.full_url);
    println!("{}", url);
}

"Agnostic" Only Feature DNS Compressor Example

Users can either build a DNS message manually using their own structures or use the DnsMessage struct provided by this library. Example with a raw buffer:

use std::collections::HashMap;
use stalkermap::dns::compressor::MessageCompressor;

let mut message = Vec::new();
let mut pointer_map = HashMap::new();

// Compress a domain name
MessageCompressor::compress("www.example.com", &mut message, &mut pointer_map).unwrap();

// Reusing the same domain (or suffix) inserts a pointer instead of repeating bytes
MessageCompressor::compress("mail.example.com", &mut message, &mut pointer_map).unwrap();

"Agnostic" Only Feature DNS Message Query Builder Example

use stalkermap::dns::resolver::agnostic::{DnsMessage, RecordType, OpCodeOptions};

// Build a query for example.com A record
let msg = DnsMessage::new_query("example.com", RecordType::A, OpCodeOptions::StandardQuery);

// Encode into raw bytes, ready to send via UDP/TCP
let bytes = msg.encode_query();

assert!(bytes.len() > 12); // includes header + question

Architecture

The library is designed with modularity and composability in mind:

utils - Core utilities for input handling and URL parsing
dns - DNS resolution and query utilities (planned)
scanner - Port scanning and network discovery (planned)
reporter - Report generation and export (planned)

Supported URL Formats

HTTP/HTTPS schemes
IPv4 and IPv6 addresses
DNS hostnames
Custom ports
Paths and query strings

Error Handling

All operations return Result<T, E> types for safe error handling:

use stalkermap::utils::{UrlParser, UrlParserErrors};

match UrlParser::new("invalid-url") {
    Ok(url) => println!("Valid URL: {}", url),
    Err(UrlParserErrors::InvalidScheme) => eprintln!("Only HTTP/HTTPS supported"),
    Err(UrlParserErrors::InvalidTargetType) => eprintln!("Invalid hostname or IP"),
    Err(e) => eprintln!("Other error: {}", e),
}

CLI Application

This repository also includes a CLI application demonstrating the library usage:

# Clone and run
git clone https://github.com/seakerOner/stalkermap-rs
cd stalkermap-rs
