Struct mongo_driver::read_prefs::ReadPrefs

pub struct ReadPrefs { /* fields omitted */ }

Provides an abstraction on top of the MongoDB connection read prefences.

It allows for hinting to the driver which nodes in a replica set should be accessed first. Generally, it makes the most sense to stick with the global default, Primary. All of the other modes come with caveats that won't be covered in great detail here.
