Struct FileCache 

pub struct FileCache { /* private fields */ }

LRU cache for file contents

Caches file contents as line vectors for fast line access. Uses a simple eviction strategy when memory limit is reached.

Implementations

impl FileCache

pub fn new(project_root: impl AsRef<Path>) -> Self

Create a new file cache with default 16MB limit

pub fn with_capacity(project_root: impl AsRef<Path>, max_bytes: usize) -> Self

Create with custom memory limit

pub fn get_line(&mut self, path: &Path, line: u32) -> Option<String>

Get a single line from a file (1-indexed)

pub fn get_range( &mut self, path: &Path, start: u32, end: u32, ) -> Option<Vec<String>>

Get multiple lines as a range (1-indexed, inclusive)
