Types

type SimpleQueryBuilder

type SimpleQueryBuilder struct {
	// contains filtered or unexported fields
}

SimpleQueryBuilder is a simple MongoDB query builder.

func (*SimpleQueryBuilder) Build

func (q *SimpleQueryBuilder) Build() bson.M

Build returns the result of the query builder as a bson.M. If Build() is called on a nil value it returns an empty bson.M that would match all documents.

func (*SimpleQueryBuilder) Where

func (q *SimpleQueryBuilder) Where(key string, operator string, value interface{}) *SimpleQueryBuilder

Where matches MongoDB documents where key matches value using operator. If Where overwrites any other "where clause" that used the same key and operator.

func (*SimpleQueryBuilder) WhereIn

func (q *SimpleQueryBuilder) WhereIn(key string, value interface{}) *SimpleQueryBuilder

WhereIn searches from MongoDB documents where the value of key is in a list of values. WhereIn addes value to this list of queried values.

type Stats

type Stats struct {
	ValidGroupBys map[string]bson.M
	ValidTimeKeys map[string]struct{}
	ValidCounts   map[string]bson.M
	Collection    *mongo.Collection
}

func (*Stats) SimpleCount

func (s *Stats) SimpleCount(ctx context.Context, counterKey string) (int, error)

func (*Stats) SimpleGroupBy

func (s *Stats) SimpleGroupBy(ctx context.Context, groupByKey string, counterKey string) ([]stats.Group, error)

func (*Stats) SimpleGroupByOverTime

func (s *Stats) SimpleGroupByOverTime(ctx context.Context, from, to time.Time, timeRange string, groupByKey, timeKey, counterKey string) ([]stats.TimeSeries, error)
