Struct vidi::util::flock::Locked

pub struct Locked<T: FileLike>(/* private fields */);

Locks a file securely (requires lockf)

This version takes ownership of the protected resource.

Not reentrant on Linux. That is, even the same thread cannot acquire the same file twice. BUT if there are two copies of this software in the same process, those copies can both lock the same file. This can happen if two different versions of the library are used, for example.

Implementations
