SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This guide addresses the need to perform safe, cross-platform system calls and file I/O in Zig without relying on std.fs or std.posix, using bun.sys wrappers for robust error handling and clearer semantics.

Core Features & Use Cases

  • Use bun.sys.File for the majority of file operations with Maybe(T) error handling, errno, and path information.
  • Access low-level file operations when needed, including opening, reading, writing, stat, and directory interactions.
  • Apply across Zig projects requiring cross-platform compatibility and strong error propagation.

Quick Start

Create a Zig function that opens a file with bun.sys.File and writes data using bun.sys wrappers.

FAQPage Schema
How do I perform file I/O in Zig without using std.fs or std.posix?▼

File I/O in Zig without std.fs or std.posix is achievable using bun.sys.File wrappers. They provide robust error handling, cross-platform system calls, and clear semantics for file operations like open, read, and write.

What is the Maybe(T) pattern for error handling in Zig system calls?▼

Maybe(T) is an error handling mechanism used with bun.sys for Zig system calls. It captures errno and path information to provide robust error propagation and clearer semantics during cross-platform file operations.

How do I open and write to a file using bun.sys in Zig?▼

To open and write to a file using bun.sys in Zig, initialize bun.sys.File with appropriate cross-platform flags, then use bun.sys wrappers to execute the write operation while managing errors via the Maybe(T) pattern.

Can I use bun.sys for cross-platform file operations in Zig?▼

Yes, bun.sys supports cross-platform file operations in Zig by providing wrappers that handle platform-specific flags and errors. It enables direct file manipulation, stat operations, and low-level system calls across different platforms.

Why should I use bun.sys instead of standard library modules for Zig system calls?▼

Using bun.sys instead of standard library modules for Zig system calls offers safer error propagation and cross-platform compatibility. The Maybe(T) pattern provides detailed errno and path tracking that standard library alternatives often lack.
