Struct DeadCodeAnalyzer 

pub struct DeadCodeAnalyzer {
    pub entry_points: Vec<String>,
}

Detect non-exported functions/classes that may be dead code.

Three signals stack:

• is_in_file_referenced — same-file usage via AST identifier scan (precise; substring matches in strings / comments don’t count).
• ctx.project.is_called_externally — cross-file call graph from parser.
• collect_token_concat_targets — for C/C++ files, scan #define ... ## macros and per-call-site invocations to recover potential function names that the macro would expand to (e.g. _handle##X##Attr paired with STYLE_DEF(color, Color, ...) produces a plausible _handleColorAttr). These names are added to the in-file reference set so X-macro dispatch tables don’t drown the file in false positives. Imperfect but vastly better than the previous “any #define ## skips the whole file” nuke.

When ctx.tree is unavailable, falls back to the legacy substring scan.

Fields

entry_points: Vec<String>

Names treated as entry points / framework callbacks. Functions with these names are never reported as dead, even when nothing else references them.

Trait Implementations

impl Default for DeadCodeAnalyzer

fn default() -> Self

Returns the “default value” for a type.

impl Plugin for DeadCodeAnalyzer

fn name(&self) -> &str

Unique identifier for this plugin.

fn smells(&self) -> Vec<String>

Smell names this plugin can produce. Used by the host for smell-level filtering, docs, and cha plugin list. Default is empty — plugins should override to declare their smells.

fn description(&self) -> &str

Short description of what the plugin detects.

fn analyze(&self, ctx: &AnalysisContext<'_>) -> Vec<Finding>

Run analysis on a single file and return findings.

fn version(&self) -> &str

Plugin version (e.g. “1.0.0”).

fn authors(&self) -> Vec<String>

List of authors.
