To set up cargo-trim to properly work for all projects related to rust lang go to directory where all projects lies and run cargo trim init. You can even run this command multiple time to add multiple directory. Or run command cargo trim set -d <directory-path>. All projects inside the directory will be used for listing orphan crates. So if there are any projects in the other directory then their dependencies will be classified as orphan crates if not used by any other crates present inside added directory.

Configuration

cargo-trim store its config file to config directory of OS and name config file as cargo_trim_config.toml. In file cargo-trim stores different information for scanning projects as well as listing crates. To list where cargo trim is storing config file you can use cargo trim config --location Below are a list of configuration and their default value a well as corresponding env variable that can be used for setting same value without editing config file

1. directory

default: []

env: TRIM_DIRECTORY

List of directory to scan for a Rust projects

2. ignore_file_name

default: []

env: TRIM_IGNORE

File/Directory name which should be ignored while scanning through directories. This can be used to exclude some folder such as npm node_modules folder or python venv folder if the directory present in config contains such folder it will help to significantly increase performance.

3. scan_hidden_folder

default: false

env: TRIM_SCAN_HIDDEN_FOLDER

Whether to scan hidden folder(i.e. folder which start with dot notation) or not

4. scan_target_folder

default: false

env: TRIM_SCAN_TARGET_FOLDER

Whether to scan target folder. Currently, it searches for environment variable CARGO_BUILD_TARGET_DIR or CARGO_TARGET_DIR or set default value as target to determine a target folder name
