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: client_pull_request.go
    path of file: ./repos/cds/engine/vcs/bitbucketserver
    
    the code of the file until where you have to start completion: package bitbucketserver

import (
	"context"
	"encoding/json"
	"fmt"
	"net/url"
	"strconv"
	"strings"
	"time"

	"github.com/ovh/cds/sdk"
	"github.com/ovh/cds/sdk/telemetry"
)

func (b *bitbucketClient) PullRequest(ctx context.Context, repo string, id string) (sdk.VCSPullRequest, error) {
	ctx, end := telemetry.Span(ctx, "bitbucketserver.PullRequest", telemetry.Tag(telemetry.TagRepositor
    
func (b *bitbucketClient) PullRequestComment(ctx context.Context, repo string, prRequest sdk.VCSPullRequestCommentRequest) error {
	project, slug, err := getRepo(repo)
	if err != nil {
		return sdk.WithStack(err)
	}

	if len(prRequest.Message) >= 32768 {
		prRequest.Message = prRequest.Message[0:32750] + "\n[truncated]"
	}

	payload := map[string]string{
		"text": prRequest.Message,
	}
	values, err := json.Marshal(payload)
	if err != nil {
		return sdk.WithStack(err)
	}

	path := fmt.Sprintf("/projects/%s/repos/%s/pull-requests/%d/comments", project, slug, prRequest.ID)

	return b.do(ctx, "POST", "core", path, nil, values, nil)
}
