You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: infracost.go
    path of file: ./repos/gitleaks/cmd/generate/config/rules
    
    the code of the file until where you have to start completion: package rules

import (
	"github.com/zricethezav/gitleaks/v8/cmd/generate/secrets"
	"github.com/zricethezav/gitleaks/v8/config"
)

func InfracostAPIToken() *config.Rule {
	// define rule
	r := config.Rule{
		// Human readable description of the rule
    
func InfracostAPIToken() *config.Rule {
	// define rule
	r := config.Rule{
		// Human readable description of the rule
		Description: "Detected an Infracost API Token, risking unauthorized access to cloud cost estimation tools and financial data.",

		// Unique ID for the rule
		RuleID: "infracost-api-token",

		// Regex capture group for the actual secret

		// Regex used for detecting secrets. See regex section below for more details
		Regex: generateUniqueTokenRegex(`ico-[a-zA-Z0-9]{32}`, true),

		// Keywords used for string matching on fragments (think of this as a prefilter)
		Keywords: []string{"ico-"},
	}

	// validate
	tps := []string{
		generateSampleSecret("ico", "ico-"+secrets.NewSecret("[A-Za-z0-9]{32}")),
	}
	return validate(r, tps, nil)
}
