package main import ( "bazil.org/fuse" "bazil.org/fuse/fs" "context" ) type MyFile struct { // ... modTime time.Time } func (f *MyFile) Attr(ctx context.Context, a *fuse.Attr) error { a.Mode = os.ModePerm a.Mtime = f.modTime // ... }In this example, `MyFile` represents a file in the FUSE file system. The `Attr` method of `MyFile` is called to get its attributes, and it sets the `Mtime` field of the `fuse.Attr` struct to the `modTime` field of the `MyFile` struct. The `bazil.org.fuse` package provides a Go library for implementing FUSE file systems.
