Implementations

impl Exif

pub fn new(root_or_exif: &IFD) -> Result<Self>

Read EXIF data. As some EXIF tags located in the root IFD, we accept both IFDs here.

pub fn extend_from_ifd(&mut self, ifd: &IFD) -> Result<()>

Extend the EXIF info from this IFD. If the IFD contains a ExifIFD, extend from this IFD, too.

pub fn extend_from_gps_ifd(&mut self, ifd: &IFD) -> Result<()>

Extend the EXIF info from this IFD. If the IFD contains a ExifIFD, extend from this IFD, too.

Trait Implementations

impl Clone for Exif

fn clone(&self) -> Exif

Returns a duplicate 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 Default for Exif

fn default() -> Exif

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Exif

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for Exif

fn cmp(&self, other: &Exif) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Exif

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

fn partial_cmp(&self, other: &Exif) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Exif

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Exif

impl StructuralPartialEq for Exif
