}

Trait for displaying a syntax node

Required Methods

fn name() -> Option<&'static str>

Name of the syntax node’s type

fn start(&self) -> Option<TextSize>

Starting position of the node

fn end(&self) -> Option<TextSize>

Ending position of the node

fn source_id(&self) -> Option<FileId>

Source id of the node

fn display(&self) -> NodeDisplayWrapper<'_, Self>

Obtain a display wrapper for the current node

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

Display extra information for the node

Parameters

• f: formatter to output to

fn display_children( &self, level: usize, f: &mut Formatter<'_>, ) -> Result<(), Error>

Display the node’s children

Parameters

• level: current indentation level
• f: formatter to output to

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
