Function atomicFile [src]

Directly access the .file field, and then call AtomicFile.finish to atomically replace dest_path with contents. Always call AtomicFile.deinit to clean up, regardless of whether AtomicFile.finish succeeded. dest_path must remain valid until AtomicFile.deinit is called. On Windows, dest_path should be encoded as WTF-8. On WASI, dest_path should be encoded as valid UTF-8. On other platforms, dest_path is an opaque sequence of bytes with no particular encoding.

Prototype

pub fn atomicFile(self: Dir, dest_path: []const u8, options: AtomicFileOptions) !AtomicFile

Parameters

self: Dirdest_path: []const u8options: AtomicFileOptions

Source

  pub fn atomicFile(self: Dir, dest_path: []const u8, options: AtomicFileOptions) !AtomicFile {
    if (fs.path.dirname(dest_path)) |dirname| {
        const dir = if (options.make_path)
            try self.makeOpenPath(dirname, .{})
        else
            try self.openDir(dirname, .{});

        return AtomicFile.init(fs.path.basename(dest_path), options.mode, dir, true);
    } else {
        return AtomicFile.init(dest_path, options.mode, self, false);
    }
}
