Aggregation Expression - $gte

Function Build

Build $gte with the Gte function from the aggregation package.

// bson.D{bson.E{Key:"isAdult", Value:bson.D{bson.E{Key:"$gte", Value:[]interface {}{"$age", 18}}}}}
result := aggregation.Gte("isAdult", "$age", 18)

Method Build (Builder)

Build $gte with the Gte method from aggregation.NewBuilder().

// bson.D{bson.E{Key:"isAdult", Value:bson.D{bson.E{Key:"$gte", Value:[]interface {}{"$age", 18}}}}}
result := aggregation.NewBuilder().
    Gte("isAdult", "$age", 18).
    Build()

Build Without Key

When an expression needs to be passed as an argument to another expression, use a WithoutKey variant to build an expression fragment without an output field name.

GteWithoutKey

Function build:

// bson.D{bson.E{Key:"$gte", Value:[]any{"$age", 18}}}
expr := aggregation.GteWithoutKey("$age", 18)

Method build (Builder):

// bson.D{bson.E{Key:"$gte", Value:[]any{"$age", 18}}}
expr := aggregation.NewBuilder().
    GteWithoutKey("$age", 18).
