prebindgen-project-root
A tiny utility crate that, when built inside a Cargo workspace, discovers the workspace root.
The main purpose of this tool is to allow a crate installed from crates.io (i.e., not part of the workspace)
to find the workspace's Cargo.lock at compile time. A simple call to the well-known
project_root::get_project_root() doesn't work here because it searches upward from the current working
directory, which during a build is inside $HOME/.cargo rather than your workspace.
This crate solves the problem by injecting itself into the user's workspace via the [patch] section.
That is, the workspace contains a copy of the prebindgen-project-root crate which, being inside the
workspace, can determine the workspace root. Any crate that depends on prebindgen-project-root will then
use the copy from the user's workspace instead of the one in $HOME/.cargo.
The Cargo subcommand prebindgen-project-root automates this injection. Run:
cargo install prebindgen-project-root
cargo prebindgen-project-root install .
