Struct LintCache 

pub struct LintCache {
    pub version: u32,
    pub config_hash: u64,
    pub entries: HashMap<String, CacheEntry>,
}

Cache for storing file hashes and lint results.

Enables incremental linting by skipping unchanged files. Cache is stored as JSON and can be persisted to disk.

Fields

version: u32

Schema version for forward compatibility

config_hash: u64

Config hash - invalidate cache if config changes

entries: HashMap<String, CacheEntry>

Cached file entries: path -> CacheEntry

Implementations

impl LintCache

pub fn new() -> Self

Create a new empty cache.

pub fn with_config(config: &LintConfig) -> Self

Create a cache with a specific config hash.

pub fn from_file(path: &Path) -> Result<Self, String>

Load cache from a JSON file.

pub fn from_json(content: &str) -> Result<Self, String>

Parse cache from JSON string.

pub fn to_file(&self, path: &Path) -> Result<(), String>

Save cache to a JSON file.

pub fn to_json(&self) -> Result<String, String>

Convert cache to JSON string.

pub fn hash_content(content: &str) -> String

Compute BLAKE3 hash of file contents.

pub fn needs_lint( &self, path: &str, content: &str, metadata: Option<&Metadata>, ) -> bool

Check if a file needs re-linting.

Returns true if:

• File is not in cache
• File content has changed (different hash)
• File metadata suggests change (mtime/size)

pub fn get_cached(&self, path: &str, content: &str) -> Option<Diagnostics>

Get cached diagnostics for a file if valid.

pub fn update( &mut self, path: &str, content: &str, diagnostics: &Diagnostics, metadata: Option<&Metadata>, )

Update cache entry for a file.

pub fn prune(&mut self, existing_files: &HashSet<String>)

Remove stale entries (files that no longer exist).

pub fn is_valid_for(&self, config: &LintConfig) -> bool

Check if cache is valid for given config.

pub fn stats(&self) -> CacheStats

Get cache statistics.
