Functions ¶
Types ¶
type BaseOperator ¶
type BaseOperator struct {
// contains filtered or unexported fields
}
BaseOperator is a simple operator struct that implementes the Operator interface.
func (*BaseOperator) GetKey ¶
func (operator *BaseOperator) GetKey() string
GetKey function returns the operator's key.
func (*BaseOperator) GetVal ¶
func (operator *BaseOperator) GetVal() interface{}
GetVal function returns the operator's value.
type Operator ¶
type Operator interface {
GetKey() string
GetVal() interface{}
}
Operator is an interface that should be implemented by structs used as operators.
func Bucket ¶
func Bucket(groupBy, boundaries, def, output interface{}) Operator
Bucket function returns a mongo $bucket operator used in aggregations.
func BucketAuto ¶
func BucketAuto(groupBy, buckets, output, granularity interface{}) Operator
BucketAuto function returns a mongo $bucketAuto operator used in aggregations.
func CollStats ¶
func CollStats(latencyStats, storageStats, count interface{}) Operator
CollStats function returns a mongo $collStats operator used in aggregations.
func CurrentOp ¶
func CurrentOp(allUsers, idleConnections, idleCursors, idleSessions, localOps interface{}) Operator
CurrentOp function returns a mongo $currentOp operator used in aggregations.
func Lookup ¶
func Lookup(from, localField, foreignField, as interface{}) Operator
Lookup function returns a mongo $lookup operator used in aggregations.
func Merge ¶
func Merge(into, on, let, whenMatched, whenNotMatched interface{}) Operator
