Struct RenderContext 

pub struct RenderContext { /* private fields */ }

What BlockNode::render needs besides the node: the text style, code highlighter and Markdown extensions.

Implementations

impl RenderContext

pub fn new(style: TextViewStyle) -> Self

Creates a local rendering context without reading application globals. The host supplies body typography through its container or with_body_font_size.

pub fn with_code_block_highlighter<F>(self, highlighter: F) -> Self

where F: Fn(&CodeBlock) -> Vec<(Range<usize>, HighlightStyle)> + Send + Sync + 'static,

Replaces code highlighting for this context only.

pub fn with_image_source<F>(self, resolver: F) -> Self

where F: Fn(&SharedUri) -> ImageSource + Send + Sync + 'static,

Resolves document image URIs. The host owns resource access policy.

pub fn on_link_click<F>(self, handler: F) -> Self

where F: Fn(&SharedString, &ClickEvent, &mut Window, &mut App) + Send + Sync + 'static,

Handles link activation. Without a handler, links use App::open_url.

pub fn with_link_reference( self, identifier: impl Into<SharedString>, link: LinkMark, ) -> Self

Registers a reference-link definition from the host’s document. Supply definitions for the entire document, including virtualized blocks.

pub fn from_app(cx: &App) -> Self

The context TextView would start from: the global TextViewDefaults style and code-block highlighter when set, else the theme’s style.

pub fn with_style(self, style: TextViewStyle) -> Self

Replaces the text style.

pub fn with_markdown_extensions( self, extensions: Arc<MarkdownExtensions>, ) -> Self

Sets the Markdown extensions that render custom nodes.

pub fn with_body_font_size(self, size: Pixels) -> Self

Sets the font size body text inherits, which the block gaps and heading sizes are relative to.

pub fn style(&self) -> &TextViewStyle

The text style blocks render with.

Trait Implementations

impl Clone for RenderContext

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
