Struct FileCache 

pub struct FileCache { /* private fields */ }

File-based cache manager for test result caching

London School TDD Design:

• Implements Cache trait for collaboration contract
• Thread-safe with Arc<Mutex<>> for concurrent access
• Proper error handling with Result<T, CleanroomError>
• No unwrap() or expect() calls

Example

use clnrm_core::cache::{FileCache, Cache};
use std::path::Path;

let cache = FileCache::new()?;
let file_path = Path::new("tests/api.clnrm.toml");
let content = "rendered content";

if cache.has_changed(file_path, content)? {
    // Run test
    cache.update(file_path, content)?;
    cache.save()?;
}

Implementations

impl FileCache

pub fn new() -> Result<Self>

Create a new cache manager with default cache directory

pub fn with_path(cache_path: PathBuf) -> Result<Self>

Create a cache manager with custom cache file path

pub fn cache_path(&self) -> &Path

Get the cache file path
