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: tl_access_point_rule_gen.go
    path of file: ./repos/td/tg
    
    the code of the file until where you have to start completion: // Code generated by gotdgen, DO NOT EDIT.

package tg

	"context"

	if a == nil {
		return fmt.Errorf("can't decode accessPointRule#4679b65f to nil")
	}
	{
		value, err := b.String()
		if err != nil {
			return fmt.Errorf("unable to decode accessPointRule#4679b65f: field phone_prefix_rules: %w", err)
