w32-error

w32-error is a Rust crate for encapsulating Windows API error codes. It provides the W32Error type, a thin wrapper over a DWORD with trait implementations for error handling.

Features

• #![no_std]-friendly - almost all of w32-error is available to #![no_std] crates. Parts that require libstd (Error trait impl, conversion to/from io::Error) are kept behind an opt-in feature gate.
• Zero overhead - W32Error is guaranteed to have the same layout as a DWORD. Display::fmt doesn't access the heap; instead, it uses a small buffer on the stack to receive error messages.

Usage

To use w32-error, simply add it to your Cargo.toml.

By default, w32-error is configured for a #![no_std] environment:

[dependencies]
w32-error = "^1.0.0"

Alternatively, features that require libstd can be manually enabled:

[dependencies]
w32-error = { version = "^1.0.0", features = ["std"] }
