Trait NodeContentDisplay

pub trait NodeContentDisplay {
    // Required methods
    fn name() -> Option<&'static str>;
    fn display_extra(&self, f: &mut Formatter<'_>) -> Result;
    fn display_children(&self, level: usize, f: &mut Formatter<'_>) -> Result;
}

Trait for displaying an AST node’s content

Required Methods

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

Name of the node

Returns

None if this node is just a transparent wrapper (and should not be displayed), otherwise the name of the node type.

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

Display extra information for the node

Parameters

• f: formatter to output to

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

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.
