Struct nom_exif::Exif

pub struct Exif { /* private fields */ }

Represents Exif information in a JPEG/HEIF file.

Please note that Exif values are lazy-parsed, meaning that they are only truly parsed when the Exif::get_value and Exif::get_values methods are called. This allows you to parse Exif values on-demand, reducing the parsing overhead.

Implementations

impl Exif

pub fn get_values<'b>( &self, tags: &'b [ExifTag] ) -> Vec<(&'b ExifTag, EntryValue)>

Searches for specified tags within the parsed Exif data, and parses the corresponding values within the found entries. The final result is returned in the form of a hash table.

Please note that this method will ignore errors encountered during the search and parsing process, such as missing tags or errors in parsing values, and handle them silently.

pub fn get_value(&self, tag: &ExifTag) -> Result<Option<EntryValue>>

Searches for specified tag within the parsed Exif structure, and parses the corresponding value within the found entry.

pub fn get_value_by_tag_code(&self, tag: u16) -> Result<Option<EntryValue>>

Searches for specified tag within the parsed Exif structure, and parses the corresponding value within the found entry.

pub fn get_gps_info(&self) -> Result<Option<GPSInfo>>

Searches and parses the found GPS information within the parsed Exif structure.

Trait Implementations

impl Clone for Exif

fn clone(&self) -> Exif

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Exif

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

Formats the value using the given formatter.

impl PartialEq for Exif

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

This method tests for self and other values to be equal, and is used by ==.

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

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