Safe bindings for the Windows Notification Facility

GitHub crates.io docs.rs license rustc 1.62+

The Windows Notification Facility (WNF) is a registrationless publisher/subscriber mechanism that was introduced in Windows 8 and forms an undocumented part of the Windows API.

This crate provides safe Rust abstractions over (a part of) this API. If you are looking for raw bindings to the API, take a look at the ntapi crate.

Note that while great care was taken in making these abstractions memory-safe, there cannot be a guarantee due to the undocumented nature of the API.


This crate is available on crates.io. In order to use it, add this to the dependencies table of your Cargo.toml:

wnf = "0.1.1"

Some functionality of this crate is only available if the corresponding features are enabled. For example, in order to enable the subscribe feature:

wnf = { version = "0.1.1", features = ["subscribe"] }

This is a Windows-only crate and will fail to compile on other platforms. If you target multiple platforms, it is recommended that you declare it as a platform specific dependency:

wnf = "0.1.1"


For a detailed explanation on how to use this crate, see the crate documentation.

For examples, see the examples folder in the crate repository.
