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: uri.go
    path of file: ./repos/sliver/vendor/github.com/aws/smithy-go/encoding/httpbinding
    
    the code of the file until where you have to start completion: package httpbinding

import (
	"math"
	"math/big"
	"strconv"
	"strings"
)

// URIValue is used to encode named URI parameters
type URIValue struct {
	path, rawPath, buffer *[]byt
    
func SplitURI(uri string) (path, query string) {
	queryStart := strings.IndexRune(uri, '?')
	if queryStart == -1 {
		path = uri
		return path, query
	}

	path = uri[:queryStart]
	if queryStart+1 >= len(uri) {
		return path, query
	}
	query = uri[queryStart+1:]

	return path, query
}
