Struct Text 

pub struct Text {
    pub text: String,
    pub marks: Vec<MarkSpan>,
}

Inline content: a string, plus marks over byte ranges of it.

Marks are a separate list rather than flags on a run because an editor has to map them through insertions and deletions, and because run flags lose nesting order — under flags **_x_** and _**x**_ are the same value. Here they differ by the order of the two spans, and both survive a round trip.

A newline in text is a line break within the block (markdown’s soft or hard break, which this model does not distinguish — neither does Notion). Whether it paints as a break or a space is a rendering decision.

Fields

text: String

marks: Vec<MarkSpan>

Outermost first. Ranges may overlap and may be identical.

Implementations

impl Text

pub fn plain(text: impl Into<String>) -> Self

Unmarked text.

pub fn link(url: &str) -> Self

A URL that links to itself — what a pasted link is, and what a bookmark hands back when it turns into prose.

pub fn is_empty(&self) -> bool

impl Text

pub fn insert(&mut self, at: usize, s: &str)

Insert at a byte offset, moving the marks with it.

pub fn remove(&mut self, range: Range<usize>)

Remove a byte range, collapsing any mark that covered it.

pub fn toggle(&mut self, range: Range<usize>, mark: Mark)

Add mark over range, or take it away if the whole range has it.

pub fn covered_by(&self, range: &Range<usize>, mark: &Mark) -> bool

Whether every byte of range already carries mark.

pub fn split_off(&mut self, at: usize) -> Text

Cut at at, returning the tail. The head keeps this Text.

pub fn append(&mut self, other: Text)

Append other, shifting its marks onto the end of this text.

Trait Implementations

impl Clone for Text

fn clone(&self) -> Text

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Text

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

Formats the value using the given formatter.

impl Default for Text

fn default() -> Text

Returns the “default value” for a type.

impl Eq for Text

impl PartialEq for Text

fn eq(&self, other: &Text) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
