Struct SelectionSource 

pub struct SelectionSource {
    pub source: String,
    pub visible: String,
    pub spans: Vec<SelectionSourceSpan>,
    pub full_selection_group: Option<String>,
}

Source-backed copy/hit-test payload for a selectable rich-text node.

visible is the logical text users point at while selecting; source is what copy should return. spans maps byte ranges in visible to byte ranges in source. A plain text leaf has one identity span. Markdown can instead map rendered words to their original markdown source, and atomic embeds such as math can map a one-byte object slot to the full $...$ / $$...$$ source.

Fields

source: String

visible: String

spans: Vec<SelectionSourceSpan>

full_selection_group: Option<String>

Implementations

pub fn visible_len(&self) -> usize

Trait Implementations

impl Clone for SelectionSource

fn clone(&self) -> SelectionSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionSource

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

Formats the value using the given formatter.

impl Default for SelectionSource

fn default() -> SelectionSource

Returns the “default value” for a type.

impl PartialEq for SelectionSource

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