Struct exif::In

pub struct In(pub u16);

An IFD number.

The IFDs are indexed from 0. The 0th IFD is for the primary image and the 1st one is for the thumbnail. Two associated constants, In::PRIMARY and In::THUMBNAIL, are defined for them respectively.

Examples

use exif::In;
assert_eq!(In::PRIMARY.index(), 0);
assert_eq!(In::THUMBNAIL.index(), 1);

Tuple Fields

0: u16

Implementations

impl In

pub const PRIMARY: In = _

pub const THUMBNAIL: In = _

pub fn index(self) -> u16

Returns the IFD number.

Trait Implementations

impl Clone for In

fn clone(&self) -> In

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for In

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

Formats the value using the given formatter.

impl Display for In

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

Formats the value using the given formatter.

impl Hash for In

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 Ord for In

fn cmp(&self, other: &In) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for In

fn eq(&self, other: &In) -> 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.

impl PartialOrd for In

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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