Variables

var DiscardFile vfs.File = (*discardFile)(nil)

DiscardFile implements vfs.File but discards all written data and reads without mutating input buffers.

Functions

func WithOpenFileTracking

func WithOpenFileTracking(inner vfs.FS) (vfs.FS, func(io.Writer))

WithOpenFileTracking wraps a FS, returning an FS that will monitor open files. The second return value is a func that when invoked prints the stacks that opened the currently open files. If no files are open, the func writes nothing.
