Struct LongFileRule 

pub struct LongFileRule {
    pub threshold: usize,
    /* private fields */
}

Rule that flags source files exceeding a line count threshold.

Fields

threshold: usize

Implementations

impl LongFileRule

pub fn new(threshold: usize, allow: &[String]) -> Self

Create a new LongFileRule with the given threshold and allow-list patterns.

Callers should pass the allow list from [rules.rule."long-file"] in config:

let allow = config.rules.rules.get("long-file").map(|r| r.allow.clone()).unwrap_or_default();
let rule = LongFileRule::new(threshold, &allow);

Trait Implementations

impl FileRule for LongFileRule

type Finding = LongFileFinding

Serializable per-file finding type.

fn engine_name(&self) -> &str

Unique engine name for cache keying (e.g. “long-function”, “high-complexity”).

fn config_hash(&self) -> String

Config hash for cache invalidation (e.g. threshold.to_string()).

fn check_file(&self, path: &Path, root: &Path) -> Vec<Self::Finding>

Check a single file. Returns findings for that file. path is absolute, root is the project root for computing relative paths.

fn to_diagnostics( &self, findings: Vec<(PathBuf, Vec<Self::Finding>)>, _root: &Path, files_checked: usize, ) -> DiagnosticsReport

Convert collected findings into a DiagnosticsReport. findings maps file path to that file’s findings. files_checked is the total number of files examined (cached + fresh).
