Build.rs Cfg

Build.rs Cfg. An alternative, slightly more complicated way, is to use # [cfg (feature = debug)] and create a build script that enables a debug feature for your crate, as shown here. The single most important rust performance tip is simple but easy to overlook:

It may take a while to build your crate, depending on how many crates are in the queue. In your lib.rs #[cfg(feature = bindgen)] include!(concat!(env!(out_dir), /bindings.rs));

Currently, Cfg Directives Do Not Work “Correctly” In A Build Script.

Display and control your pc and android devices from anywhere at anytime. This is because the build script must be compiled for the host machine to execute. Clone of flipper zero firmware.

The Single Most Important Rust Performance Tip Is Simple But Easy To Overlook:

By default cargo looks up for build.rs file in a package root (even if you do not specify a value for build). Some common build script functionality can be found via crates on crates.io.check out the. [package] build = build.rs second, we create.

In Your Lib.rs #[Cfg(Feature = Bindgen)] Include!(Concat!(Env!(Out_Dir), /Bindings.rs));

Docs.rs automatically builds documentation for crates released on crates.io. The following sections illustrate some examples of writing build scripts. Automatic derive config object, see fromconfig.

Another Possibility Is Using Cfg As A Directive To Avoid Building Winres On Unix Platforms Alltogether.
