Module helmlint 

Helmlint-RS: Native Rust Helm Chart Linter

A Rust implementation of a comprehensive Helm chart linter, inspired by and partially derived from the helmtest project.

Features

• Chart.yaml validation (structure, versions, dependencies)
• values.yaml validation (types, schema, unused values)
• Template syntax analysis (unclosed blocks, undefined variables)
• Security checks (privileged containers, host access)
• Best practice validation (resource limits, probes, deprecated APIs)
• Inline pragma support for ignoring rules

Example

use syncable_cli::analyzer::helmlint::{lint_chart, HelmlintConfig, LintResult};
use std::path::Path;

let config = HelmlintConfig::default();
let result = lint_chart(Path::new("./my-chart"), &config);

for failure in result.failures {
    println!("{}: {} - {}", failure.file, failure.code, failure.message);
}
