Overview

Package camtypes is like the types package, but higher-level and contains Perkeep-specific types. It exists mostly to break circular dependencies between index, search, and schema.

var (
	ErrClientNoServer = addCamError("client-no-server", funcStr(func() string {
		return fmt.Sprintf("No valid server defined. It can be set with the CAMLI_SERVER environment variable, or the --server flag, or in the \"servers\" section of %q (see https://perkeep.org/doc/client-config).", osutil.UserClientConfigPath())
	}))
	ErrClientNoPublicKey = addCamError("client-no-public-key", str("No public key configured: see 'pk-put init'."))
)

Functions

func Err 

func Err(key string) error

Err returns the error registered for key. It panics for an unregistered key.

Types

type BlobMeta 

type BlobMeta struct {
	Ref  blob.Ref
	Size uint32

	// CamliType is non-empty if this blob is a Perkeep JSON
	// schema blob. If so, this is its "camliType" attribute.
	CamliType schema.CamliType
}

BlobMeta is the metadata kept for each known blob in the in-memory search index. It's kept as small as possible to save memory.

type Claim

	StorageInitTime types.Time3339 `json:"storageInitTime,omitempty"`

	ThumbVersion string `json:"thumbVersion"` // Thumbnailing version.

	// AuthToken is an auth.OpAll token used by the web UI and the WebSocket.
	// It is randomly generated the first time discovery is served.
	AuthToken string `json:"authToken"`

	// HasLegacySHA1Index reports whether this server
	// contains legacy SHA-1 sums of files in its wholeref
	// index. When true, clients can additional compute the SHA-1 of
	// local files to upload to avoid uploading duplicates.
	HasLegacySHA1Index bool `json:"hasLegacySHA1Index"`

	BlobRef   blob.Ref // the blob responsible for the edge relationship
}

func (*Edge) String 

func (e *Edge) String() string

	Height uint16 `json:"height"`
}

ImageInfo describes an image file.

The Width and Height are uint16s to save memory in index/corpus.go, and that's the max size of a JPEG anyway. If we want to deal with larger sizes, we can use MaxUint16 as a sentinel to mean to look elsewhere. Or ditch this optimization.

type Location 

type Location struct {
	// Latitude and Longitude represent the point location of this blob,
	// such as the place where a photo was taken.
