Enum CommentPosition 

pub enum CommentPosition {
    Leading,
    Trailing,
    Between(usize),
    Standalone,
}

Position of a comment relative to AST nodes.

Comments can appear in various positions relative to the code they document, and this enum captures those relationships for proper formatting and preservation during transformations.

Variants

Leading

Comment appears before the associated AST node

Trailing

Comment appears after the associated AST node on the same line

Between(usize)

Comment appears between elements in a container (index of preceding element)

Standalone

Standalone comment not associated with any specific AST node

Trait Implementations

impl Clone for CommentPosition

fn clone(&self) -> CommentPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommentPosition

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

Formats the value using the given formatter.

impl PartialEq for CommentPosition

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