[−][src]Struct rexif::ExifEntry
Structure that represents a parsed EXIF tag.
Fields
namespace: Namespace
Namespace of the tag. If Standard (0x0000), it is an EXIF tag defined in the official standard. Other namespaces accomodate manufacturer-specific tags that may be embedded in MarkerNote blob tag.
ifd: IfdEntry
Low-level IFD entry that contains the EXIF tag. The client may look into this
structure to get tag's raw data, or to parse the tag herself if tag
is UnknownToMe
.
tag: ExifTag
EXIF tag type as an enumeration. If UnknownToMe
, the crate did not know the
tag in detail, and parsing will be incomplete. The client may read into
ifd
to discover more about the unparsed tag.
value: TagValue
EXIF tag value as an enumeration. Behaves as a "variant" value
unit: String
Unit of the value, if applicable. If tag is UnknownToMe
, unit will be empty.
If the tag has been parsed and it is indeed unitless, it will be "none"
.
Note that
unit refers to the contents of value
, not to the readable string. For example,
a GPS latitude is a triplet of rational values, so unit is D/M/S, even though
value_more_readable
contains a single string with all three parts
combined.
value_more_readable: String
Human-readable and "pretty" version of value
.
Enumerations and tuples are interpreted and combined. If value
has a unit, it is also added.
If tag is UnknownToMe
,
this member contains the same string as value_readable
.
