Enum TagOrCode 

pub enum TagOrCode {
    Tag(ExifTag),
    Unknown(u16),
}

Either a recognized ExifTag or a raw u16 tag code that the parser did not recognize. Yielded by crate::ExifIterEntry::tag and by crate::ExifEntry::tag.

Variants

Tag(ExifTag)

Tag is in the recognized ExifTag enum.

Unknown(u16)

Tag is not in ExifTag; raw u16 code is preserved.

Implementations

impl TagOrCode

pub fn tag(&self) -> Option<ExifTag>

The recognized ExifTag, if any. None for Unknown(_).

pub fn code(&self) -> u16

The raw u16 tag code (always available, recognized or not).

Trait Implementations

impl Clone for TagOrCode

fn clone(&self) -> TagOrCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TagOrCode

impl Debug for TagOrCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TagOrCode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TagOrCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TagOrCode

impl From<u16> for TagOrCode

fn from(v: u16) -> Self

Converts to this type from the input type.

impl Hash for TagOrCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TagOrCode

fn eq(&self, other: &TagOrCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TagOrCode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
