pub struct ImmutableMappedMutexGuard<'a, R: RawMutex, T: ?Sized> { /* private fields */ }

Expand description

A mutex guard that has an exclusive lock, but only an immutable reference; useful if you need to map a mutex guard with a function that returns an &T. Construct using the MapImmutable trait.
