Struct btlib::atomic_file::SyncFile

pub struct SyncFile<T> { /* private fields */ }

This struct provides synchronized access to a file such that two different processes cannot concurrently write to the same path.

Implementations

impl<T> SyncFile<T>

pub fn new(path: PathBuf, mask: u32) -> Self

Create a new SyncFile backed by path. If there is no file at path, then it will be created and it’s mode adjusted according to mask.

impl<T: Serialize> SyncFile<T>

pub fn save(&self, value: &T) -> Result<()>

Serialize value and save the resulting bytes in the file.

impl<T: TryDefault + Serialize + DeserializeOwned> SyncFile<T>

pub fn load_or_init(&self) -> Result<T>

Load the current value from the file, or create a new value using the TryDefault trait, save it to the file and return it.
