Struct OcrState 

pub(super) struct OcrState {
    boxes: Vec<OcrBox>,
    image: (f64, f64),
    selected: BTreeSet<usize>,
    anchor: Option<usize>,
    hovered: Option<usize>,
}

Boxes in reading order, plus what is selected and hovered; indices refer to that order.

Fields

boxes: Vec<OcrBox>

image: (f64, f64)

selected: BTreeSet<usize>

anchor: Option<usize>

Box a Shift-click or drag extends from.

hovered: Option<usize>

Implementations

impl OcrState

pub(super) fn new(boxes: Vec<OcrBox>, image: (f64, f64)) -> Self

image is the displayed texture’s size, used to place the normalized boxes.

pub(super) fn boxes(&self) -> &[OcrBox]

pub(super) fn image(&self) -> (f64, f64)

pub(super) fn is_selected(&self, idx: usize) -> bool

pub(super) fn hovered(&self) -> Option<usize>

pub(super) fn set_hovered(&mut self, idx: Option<usize>) -> bool

Returns whether the hovered box changed, so callers redraw only when needed.

pub(super) fn box_at(&self, area: (f64, f64), p: (f64, f64)) -> Option<usize>

Topmost box under p, in the coordinates of a widget of size area.

pub(super) fn press(&mut self, idx: usize, shift: bool, ctrl: bool) -> bool

Mouse press on a box; returns whether dragging should extend the selection.

pub(super) fn click(&mut self, idx: usize, extend: bool)

Selects only idx, or toggles it when extend is set.

pub(super) fn extend_to(&mut self, idx: usize)

Selects every box between the anchor and idx.

pub(super) fn select_all(&mut self)

pub(super) fn clear_selection(&mut self)

pub(super) fn has_selection(&self) -> bool

pub(super) fn selected_text(&self) -> Option<String>

Selected boxes’ text, one per line in reading order.

pub(super) fn all_text(&self) -> Option<String>

Every box’s text, one per line in reading order.

fn join_text(&self, indices: impl Iterator<Item = usize>) -> Option<String>

Trait Implementations

impl Debug for OcrState

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

Formats the value using the given formatter.

impl Default for OcrState

fn default() -> OcrState

Returns the “default value” for a type.
