dynpath

Documentation

This crate provides a #[dynpath()] macro that can be placed on a mod statement, and which points the module to a dynamic path.

The primary purpose of this crate is to include bindgen-generated bindings without an include!() statement. This allows for code completion and cross-references.

The macro takes a single parameter which is the name of an environment variable to read the path from, and it appends the module name and .rs extension onto the contents of the variable.

Example

// Turns into `#[path = "whatever/is/in/OUT_DIR/bindings.rs"]`.
#[dynpath("OUT_DIR")]
mod bindings;
