Enum TriviaKind 

#[non_exhaustive]
pub enum TriviaKind {
    LineComment,
    BlockComment,
    CppDirective,
    BlankLines(usize),
}

Source text the lexer consumes but the parser never sees.

Carries exact byte spans so a printer can re-attach comments to nearby AST nodes (which already have positions) and reproduce the original bytes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LineComment

-- ... to end of line (newline not included).

BlockComment

{- ... -}, possibly nested; unterminated runs to EOF.

CppDirective

#ifdef/#endif/… preprocessor line at column 1.

BlankLines(usize)

A run of N whitespace-only lines between tokens/comments.

Trait Implementations

impl Clone for TriviaKind

fn clone(&self) -> TriviaKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TriviaKind

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

Formats the value using the given formatter.

impl Eq for TriviaKind

impl PartialEq for TriviaKind

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