expr

var Int = intOp(func(v int64) IntField {
	return exactField(v)
})

Int is a callable factory for integer search field expressions. Calling it directly produces an exact-match field; methods produce lookups.

type UserSearchParams struct {
    Uid expr.IntField `json:"uid,omitempty"`
}

UserSearchParams{Uid: expr.Int(42)}             // ?uid=42
UserSearchParams{Uid: expr.Int.GT(1000)}        // ?uid__gt=1000
UserSearchParams{Uid: expr.Int.GTE(1000)}       // ?uid__gte=1000
UserSearchParams{Uid: expr.Int.In(1, 2, 3)}     // ?uid__in=1,2,3  (PK fields only)
UserSearchParams{Uid: expr.Int.NotGTE(9999)}    // ?uid__not_gte=9999

var Str = strOp(func(v string) StrField {
	return exactField(v)
})

Str is a callable factory for string search field expressions. Calling it directly produces an exact-match field; methods produce lookups.

type UserSearchParams struct {
    Name expr.StrField `json:"name,omitempty"`
}

UserSearchParams{Name: expr.Str("admin")}              // ?name=admin
UserSearchParams{Name: expr.Str.StartsWith("sys")}     // ?name__startswith=sys
UserSearchParams{Name: expr.Str.IContains("adm")}      // ?name__icontains=adm
UserSearchParams{Name: expr.Str.Regex(`^sys\d+`)}      // ?name__regex=^sys\d+
UserSearchParams{Name: expr.Str.In("alice", "bob")}    // ?name__in=alice,bob
UserSearchParams{Name: expr.Str.NotContains("test")}   // ?name__not_contains=test
