Struct PerformanceLinter 

pub struct PerformanceLinter { /* private fields */ }

AST-based performance linter for GUI/TUI applications

This linter analyzes code patterns that commonly cause performance issues in render/update paths.

Usage

use fastui_cosmic::perf_lints::{PerformanceLinter, lint_codes::*};

let mut linter = PerformanceLinter::new();
linter.enable(EXPENSIVE_CLONE);
linter.enable(ALLOCATION_IN_LOOP);
linter.enable(SLOW_HASHER);

let issues = linter.lint_source(source_code);
for issue in issues {
    println!("{}: {}", issue.code, issue.message);
}

Implementations

impl PerformanceLinter

pub fn new() -> Self

Create a new PerformanceLinter with all rules enabled

pub fn enable(&mut self, rule: &'static str)

Enable a specific lint rule

pub fn disable(&mut self, rule: &'static str)

Disable a specific lint rule

pub fn enabled_rules(&self) -> &[&'static str]

Get list of enabled rules

pub fn is_enabled(&self, rule: &str) -> bool

Check if a rule is enabled

impl PerformanceLinter

pub fn lint_source(&self, source: &str) -> Vec<LintIssue>

Lint source code for performance issues

This performs simple pattern matching on the source code. For full AST-based linting, use a clippy integration.
