Struct CouplingArgs 

pub struct CouplingArgs {
    pub path_a: PathBuf,
    pub path_b: Option<PathBuf>,
    pub timeout: u64,
    pub project_root: Option<PathBuf>,
    pub max_pairs: usize,
    pub top: usize,
    pub cycles_only: bool,
    pub include_tests: bool,
    pub lang: Option<Language>,
}

Analyze coupling between source modules.

Two modes:

• Pair mode (2 args): tldr coupling file_a file_b – compare two files
• Project-wide mode (1 arg): tldr coupling directory/ – scan all pairs

Measures cross-module function calls and computes a coupling score. A lower score indicates looser coupling (good), while a higher score indicates tighter coupling (may need refactoring).

Supports: Python, Go, Rust, TypeScript, JavaScript, Java, C, C++, Ruby, C#, PHP, Scala, Elixir, Lua, Luau, OCaml.

Fields

path_a: PathBuf

First source module (pair mode) or directory to scan (project-wide mode)

path_b: Option<PathBuf>

Second source module (pair mode). Omit for project-wide scan.

timeout: u64

Timeout in seconds (TIGER E02 mitigation)

project_root: Option<PathBuf>

Project root for path validation (optional)

max_pairs: usize

Maximum number of pairs to show in project-wide mode (default: 20)

top: usize

Limit output to top N modules ranked by instability (project-wide mode only). 0 = show all.

cycles_only: bool

Only show modules involved in dependency cycles (project-wide mode only)

include_tests: bool

Include test files in analysis (excluded by default)

lang: Option<Language>

Language filter (auto-detected if omitted)

Trait Implementations

impl Args for CouplingArgs

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Clone for CouplingArgs

fn clone(&self) -> CouplingArgs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CouplingArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromArgMatches for CouplingArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.
