Struct FileCache 

pub struct FileCache { /* private fields */ }

A cache that tracks file content and returns diffs on re-reads.

Uses kovan-map’s lock-free HashMap — safe for concurrent access from multiple async tasks.

Implementations

impl FileCache

pub fn new() -> Self

Create a new file cache.

pub fn read_file(&self, path: &str) -> Result<ReadResult>

Read a file, returning a cache-aware result.

• First read: returns full content (Fresh).
• Subsequent read, unchanged: returns Unchanged.
• Subsequent read, modified: returns a unified diff (Modified).

pub fn read_file_range( &self, path: &str, offset: usize, limit: usize, ) -> Result<ReadResult>

Read a range of lines from a file.

offset is 0-based line index, limit is number of lines. Caching still operates on the full file content.

pub fn stats(&self) -> CacheStats

Get cache statistics.

pub fn clear(&self)

Clear the entire cache.

pub fn invalidate(&self, path: &str)

Invalidate a single file entry.

Trait Implementations

impl Default for FileCache

fn default() -> Self

Returns the “default value” for a type.
