Enum CommentMode 

pub enum CommentMode {
    Delete,
    Preserve,
    Auto,
}

How to handle comments during formatting.

Variants

Delete

Delete all comments from output.

Preserve

Preserve comments. Line comments prevent ANY compaction.

Auto

Smart mode: preserve in multiline, convert // foo → /* foo */ only when depth/type rules force compaction. Length-based compaction is still blocked by line comments.

Trait Implementations

impl Clone for CommentMode

fn clone(&self) -> CommentMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommentMode

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

Formats the value using the given formatter.

impl Default for CommentMode

fn default() -> CommentMode

Returns the “default value” for a type.

impl PartialEq for CommentMode

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