Function locate_project_root

Source 
pub fn locate_project_root() -> Result<PathBuf>
Expand description

Searches for a project root dir, which is a directory that contains a .git dir as its direct child (it should also be the root of the project’s Rust crate or cargo workspace).

It uses the following steps:

  1. Use the value of $GIT_DIR env variable if it is present. (This variable is set by git when it invokes current process as a hook).
  2. Fallback to the output of git rev-parse --show-toplevel.
