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: compat.go
    path of file: ./repos/podman/vendor/github.com/containers/image/v5/internal/imagedestination/impl
    
    the code of the file until where you have to start completion: package impl

import (
	"context"
	"io"

	"github.com/containers/image/v5/internal/blobinfocache"
	"github.com/containers/image/v5/internal/private"
	"github.com/containers/image/v5/internal/signature"
	"github.com/containers/image/v5/types"
	"github.com/opencontainers/go-digest"
)

// Compat implements the obsolete parts of types.ImageDestination
// for implementations of private.ImageDestination.
// See AddCompat below.
type Compat struct {
	dest private.ImageDestinationInternalOnly
}

// AddCompat ini
    
func (c *Compat) TryReusingBlob(ctx context.Context, info types.BlobInfo, cache types.BlobInfoCache, canSubstitute bool) (bool, types.BlobInfo, error) {
	reused, blob, err := c.dest.TryReusingBlobWithOptions(ctx, info, private.TryReusingBlobOptions{
		Cache:         blobinfocache.FromBlobInfoCache(cache),
		CanSubstitute: canSubstitute,
	})
	if !reused || err != nil {
		return reused, types.BlobInfo{}, err
	}
	res := types.BlobInfo{
		Digest:               blob.Digest,
		Size:                 blob.Size,
		CompressionOperation: blob.CompressionOperation,
		CompressionAlgorithm: blob.CompressionAlgorithm,
	}
	// This is probably not necessary; we preserve MediaType to decrease risks of breaking for external callers.
	// Some transports were not setting the MediaType field anyway, and others were setting the old value on substitution;
	// provide the value in cases where it is likely to be correct.
	if blob.Digest == info.Digest {
		res.MediaType = info.MediaType
	}
	return true, res, nil
