Defines recognized Exif tags. All tags can be parsed, no matter if it is defined here. This enum definition is just for ease of use.

You can always get the entry value by raw tag code which is an u16 value. See ExifIterEntry::tag (returns TagOrCode which exposes .code()) and Exif::get_by_code.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl ExifTag

pub const fn code(self) -> u16

pub const fn name(self) -> &'static str

pub fn from_code_in(kind: IfdKind, code: u16) -> Option<Self>

Resolve a raw code within a known IFD namespace.

Unlike Self::from_code this cannot mislabel: a code that the given namespace does not define returns None rather than falling through to some other namespace’s meaning.

pub fn namespace(self) -> Option<IfdKind>

The namespace that defines this tag, but only when its code is ambiguous — i.e. some other IFD assigns a different tag to the same code. Returns None for codes with a single meaning, which can safely be looked up in any namespace.

use nom_exif::{ExifTag, IfdKind};

assert_eq!(ExifTag::GPSDOP.namespace(), Some(IfdKind::Gps));
assert_eq!(ExifTag::ProcessingSoftware.namespace(), Some(IfdKind::Tiff));
assert_eq!(ExifTag::Make.namespace(), None); // 0x010f means Make everywhere

pub fn from_code(code: u16) -> Option<Self>
