SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps Zig developers access low-level system calls and robust file I/O through bun.sys, avoiding direct dependencies on std.fs or std.posix while ensuring cross-platform compatibility and strong error handling.

Core Features & Use Cases

bun.sys.File wrapper for common file operations and safe resource management.
Low-level bun.sys functions for advanced IO, errno-aware error reporting, and direct syscall control.
Use cases include building cross-platform utilities, file management tools, and performance-critical Zig binaries that require precise IO behavior.

Quick Start

Try using bun.sys.File to open a file and read its contents.

FAQPage Schema

How do I perform cross-platform file I/O in Zig without relying on std.fs?▼

You can perform cross-platform file I/O in Zig by using the bun.sys.File wrapper, which provides safe resource management and common file operations without relying on std.fs. It ensures reliable behavior across platforms.

What is the best way to handle system call errors in Zig?▼

The best way to handle system call errors in Zig is using bun.sys wrappers that return Maybe(T) patterns with structured, errno-aware error information. This provides precise error reporting for low-level syscall control.

Can I use bun.sys for low-level system calls and direct syscall access in Zig?▼

Yes, you can use bun.sys for low-level system calls in Zig. It provides advanced IO functions and direct syscall control, allowing you to build performance-critical binaries that require precise IO behavior.

Does bun.sys work for building cross-platform utilities in Zig?▼

Yes, bun.sys works for building cross-platform utilities in Zig. It applies to file management tools and low-level utilities by ensuring cross-platform compatibility and strong error handling for direct syscall access.

Why should I use bun.sys wrappers instead of std.posix for file operations?▼

You should use bun.sys wrappers instead of std.posix to ensure cross-platform compatibility and robust error handling. bun.sys provides Maybe(T) patterns and structured errno-aware error reporting for reliable file operations.
