Struct AnnotatedString 

pub struct AnnotatedString {
    pub text: String,
    pub span_styles: Vec<RangeStyle<SpanStyle>>,
    pub paragraph_styles: Vec<RangeStyle<ParagraphStyle>>,
}

The basic data structure of text with multiple styles.

To construct an AnnotatedString you can use AnnotatedString::builder().

Fields

text: String

span_styles: Vec<RangeStyle<SpanStyle>>

paragraph_styles: Vec<RangeStyle<ParagraphStyle>>

Implementations

impl AnnotatedString

pub fn new(text: String) -> Self

pub fn builder() -> Builder

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn span_boundaries(&self) -> Vec<usize>

Returns a sorted list of unique byte indices where styles change.

pub fn span_styles_hash(&self) -> u64

Computes a hash representing the contents of the span styles, suitable for cache invalidation.

pub fn subsequence(&self, range: Range<usize>) -> Self

Returns a new AnnotatedString containing a substring of the original text and any styles that overlap with the new range, with indices adjusted.

Trait Implementations

impl Clone for AnnotatedString

fn clone(&self) -> AnnotatedString

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnnotatedString

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

Formats the value using the given formatter.

impl Default for AnnotatedString

fn default() -> AnnotatedString

Returns the “default value” for a type.

impl From<&String> for AnnotatedString

fn from(text: &String) -> Self

Converts to this type from the input type.

impl From<&mut String> for AnnotatedString

fn from(text: &mut String) -> Self

Converts to this type from the input type.

impl From<&str> for AnnotatedString

fn from(text: &str) -> Self

Converts to this type from the input type.

impl From<String> for AnnotatedString

fn from(text: String) -> Self

Converts to this type from the input type.

impl PartialEq for AnnotatedString

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