name: String

Canonical tag name (e.g., “ExposureTime”, “Artist”, “GPSLatitude”)

description: String

Implementations

impl Tag

pub fn priority_rank(&self) -> i32

The priority as a plain comparable number, with PRIORITY_EXPLICIT_ZERO folded back to the 0 it stands for.

Use it wherever priorities are merely ranked against each other. Only the duplicate arbitration needs to tell a table-stated 0 from an unstated priority, and it reads Tag::priority directly.

pub fn display_value(&self, numeric: bool) -> String

Get the display value respecting the print_conv option. When numeric is true (-n flag), returns the raw value. When numeric is false, returns the print-converted value.

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.
