srcfiles

A tool for searching source files used to compile a Rust crate.

Usage

srcfiles path/to/root.rs

Prints best-effort representation of all .rs and include! files used to compile a crate (currently only with debug output)

lib.rs:

Extract list of source files for Rust crate

This crate will attempt to generate a list of source files for a given Rust crate. It does not compile the crate, and so does not require any of the crate's dependencies to be compiled.

For example, this is useful for generating a list of source files as dependencies for a non-Cargo build system.

There are a number of limitations with this:

• Only works on Rust 2018 code (TODO: check 2021)
• Will not file source files which are hidden by a macro or proc-macro
• Will be confused by conditional includes

There is some specific support for the cfg_if macro.

Example

let result = srcfiles::crate_srcfiles("test_projects/simple/src/main.rs").unwrap_err();
let srcfiles = result.get_sources();
let errors = result.into_errors();
assert_eq!(srcfiles.len(), 7);
