Module diagnostics 

Rust compiler diagnostic parsing.

This module provides types and a parser for rustc --error-format=json output. Each line of stderr from rustc in JSON mode is a JSON object containing diagnostic information. This module parses those objects into structured RustDiagnostic values.

Example

use adk_code::diagnostics::parse_diagnostics;

let stderr = r#"{"message":"expected `;`","code":{"code":"E0308","explanation":null},"level":"error","spans":[{"file_name":"main.rs","byte_start":10,"byte_end":11,"line_start":1,"line_end":1,"column_start":11,"column_end":12,"is_primary":true,"text":[{"text":"let x = 1","highlight_start":11,"highlight_end":12}],"label":null,"suggested_replacement":null,"suggestion_applicability":null,"expansion":null}],"children":[],"rendered":"error: expected `;`"}"#;
let diagnostics = parse_diagnostics(stderr);
assert_eq!(diagnostics.len(), 1);
assert_eq!(diagnostics[0].level, "error");
