Function find_repository_root_from

atomic-cli/src/commands/mod.rs:269–298

Find the repository root starting from a specific path. Like [`find_repository_root`], but starts from the given path instead of the current working directory. # Arguments `start_path` - The path to start searching from # Returns The path to the repository root. # Errors Returns [`CliError::RepositoryNotFound`] if no `.atomic` directory is found. # Example ```rust,ignore let repo_root = f

(start_path: &Path)

/// let repo_root = find_repository_root_from("/home/user/project/src")?;
