Struct LockedFile 

pub struct LockedFile { /* private fields */ }

A locked file that provides safe read/write access.

This is a convenience wrapper that combines file locking with read/write operations in a single API.

Implementations

impl LockedFile

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

Creates a new locked file handle for the given path.

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

Reads the file contents with a shared lock.

If the file doesn’t exist, returns an empty string.

pub fn write(&self, path: &Path, content: &str) -> Result<()>

Writes content to the file with an exclusive lock.

pub fn with_shared_lock<T, F>(&self, f: F) -> Result<T>

where F: FnOnce() -> Result<T>,

Executes a read operation with a shared lock.

pub fn with_exclusive_lock<T, F>(&self, f: F) -> Result<T>

where F: FnOnce() -> Result<T>,

Executes a write operation with an exclusive lock.
