Pull Request Overview

This PR refactors the module mount load in Rust to build a module mount tree and support zygisk and magisk nodes, along with various mount operations.

• Added new features and module support in native/src/core/lib.rs for deploying modules.
• Modified error logging behavior in native/src/base/result.rs and improved file/dir operations in native/src/base/files.rs and native/src/base/dir.rs.
• Introduced resize functionality in native/src/base/cstr.rs for both Utf8CString and FsPathBuf.

• [nitpick] Consider using a slice type (&[ModuleInfo]) instead of &Vec for improved flexibility and idiomatic Rust usage.

fn deploy_modules(module_list: &Vec<ModuleInfo>, zygisk_lib: &CxxString, magisk_path: &CxxString) -> bool;

The Utf8CString resize method silently returns if len is greater than or equal to capacity. It might be better to handle this case explicitly (e.g., by returning a Result or panicking) to avoid unintended behavior.

Suggested change

	fn resize(&mut self, len: usize) {
	if len >= self.0.capacity() {
	return;
	fn resize(&mut self, len: usize) -> Result<(), &'static str> {
	if len >= self.0.capacity() {
	return Err("Length exceeds capacity");

[Copilot]

The FsPathBuf resize method lacks a bounds check on the provided len, which may lead to out-of-bound access. Consider adding a check to ensure len is within the valid range.

Suggested change

	unsafe {
	self.0.as_bytes_mut()[len] = b'\0';
	self.0.set_len(len)
	};
	if len <= self.0.as_bytes().len() {
	unsafe {
	self.0.as_bytes_mut()[len] = b'\0';
	self.0.set_len(len)
	};
	} else {
	// Handle the error case, e.g., by returning self unchanged or logging an error
	// For now, we will just return self unchanged
	}
