Get fields set to unique in schema from Mongoose

I have a desire to check which fields in a schema are set to unique, similar to getting the indexes for a schema via MyCollection.collection.getIndexes(). Can this information be found somewhere on the schema object?

Try this:

var schema = new mongoose.Schema({
  a: {
    type: String,
    unique: true
  },
  b: {
    type: String
  }
});

schema.tree.a.unique; // true
schema.tree.b.unique; // undefined

schema.path('a').options.unique; // true
schema.path('b').options.unique; // undefined
