Struct Field 

pub struct Field {
    pub tag: u16,
    pub value: Value,
}

One field (entry) of an Image File Directory: a tag and its value.

On disk this is a 12-byte (classic) or 20-byte (BigTIFF) record — tag, field type, value count, and a value-or-offset word — but once decoded only the tag and the resolved Value matter; the field type and count are recoverable from the value.

Fields

tag: u16

The 16-bit tag identifying the field (e.g. 256 for ImageWidth).

value: Value

The field’s value.

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.

impl PartialEq for Field

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