Struct Builder 

pub struct Builder { /* private fields */ }

A builder to construct AnnotatedString.

Implementations

impl Builder

pub fn new() -> Builder

pub fn append(self, text: &str) -> Builder

Appends the given String to this Builder.

pub fn push_style(self, style: SpanStyle) -> Builder

Applies the given SpanStyle to any appended text until a corresponding pop is called.

Returns the index of the pushed style, which can be passed to pop_to or used as an ID.

pub fn push_paragraph_style(self, style: ParagraphStyle) -> Builder

Applies the given ParagraphStyle to any appended text until a corresponding pop is called.

pub fn push_string_annotation(self, tag: &str, annotation: &str) -> Builder

Pushes a string annotation covering subsequent appended text until the matching pop.

JC parity: Builder.pushStringAnnotation(tag, annotation)

pub fn push_link(self, link: LinkAnnotation) -> Builder

Pushes a LinkAnnotation covering subsequent appended text. Call [pop] when done, or use [with_link] for the block form.

JC parity: Builder.pushLink(link)

pub fn with_link( self, link: LinkAnnotation, block: impl FnOnce(Builder) -> Builder, ) -> Builder

Block form of [push_link] — mirrors JC’s withLink(link) { ... } DSL.

Example

builder
    .append("Visit ")
    .with_link(
        LinkAnnotation::Url("https://developer.android.com".into()),
        |b| b.append("Android Developers"),
    )
    .append(".")
    .to_annotated_string()

pub fn pop(self) -> Builder

Ends the style that was most recently pushed.

pub fn to_annotated_string(self) -> AnnotatedString

Completes the builder, resolving open styles to the end of the text.
