Structured page metrics for progress and navigation.

Fields

chapter_index: usize

Chapter index in the spine (0-based), when known.

chapter_page_index: usize

Page index in chapter (0-based).

chapter_page_count: Option<usize>

Total pages in chapter, when known.

global_page_index: Option<usize>

Global page index across rendered stream (0-based), when known.

global_page_count_estimate: Option<usize>

Estimated global page count, when known.

progress_chapter: f32

Chapter progress in range [0.0, 1.0].

progress_book: Option<f32>

Book progress in range [0.0, 1.0], when known.

Trait Implementations

impl Clone for PageMetrics

fn clone(&self) -> PageMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PageMetrics

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

Formats the value using the given formatter.

impl Default for PageMetrics

fn default() -> PageMetrics

Returns the “default value” for a type.

impl PartialEq for PageMetrics

fn eq(&self, other: &PageMetrics) -> 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 Copy for PageMetrics
