CognitiveComplexityAnalyzer

Struct CognitiveComplexityAnalyzer 

Source
pub struct CognitiveComplexityAnalyzer {
    pub threshold: usize,
}
Expand description

Detect functions with high cognitive complexity.

Cognitive complexity measures how hard code is to understand, unlike cyclomatic complexity which measures testability. It penalizes nesting and rewards linear, readable structures like switch.
