Crate hexspell

HexSpell

HexSpell is a collection of helpers for inspecting and mutating executable formats. It focuses on providing a small, predictable API that mirrors the underlying file layout so that programs can tweak headers or sections without rebuilding the whole file.

The crate is split into dedicated modules for the PE, ELF, and Mach-O formats. Each module exposes types for reading a binary from disk, modifying its fields in place, and writing the result back. Common building blocks such as Field and shared error definitions live in sibling modules.

Basic usage revolves around choosing a format module and loading a file:

use hexspell::pe::PE;
let pe = PE::from_file("tests/samples/sample1.exe").unwrap();
println!("sections: {:?}", pe.header.entry_point.value);

From there values can be changed using the provided Field helpers and persisted with write_file.
