Struct Paren

pub struct Paren {
    pub expr: Box<Expr>,
    pub span: Range<usize>,
}

A parenthesized expression. A Paren can only contain a single expression.

Fields

expr: Box<Expr>

The inner expression.

span: Range<usize>

The region of the source code that this Paren was parsed from.

Implementations

impl Paren

pub fn span(&self) -> Range<usize>

Returns the span of the parenthesized expression.

pub fn innermost(&self) -> &Expr

Returns the innermost expression in the parenthesized expression.

pub fn into_innermost(self) -> Expr

Returns the innermost expression in the parenthesized expression, consuming the Paren.

Trait Implementations

impl Clone for Paren

fn clone(&self) -> Paren

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Paren

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

Formats the value using the given formatter.

impl Display for Paren

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

Formats the value using the given formatter.

impl Latex for Paren

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

Format the value as LaTeX.

fn as_display(&self) -> LatexFormatter<'_, Self>

Wraps the value in a LatexFormatter, which implements Display.

impl<'source> Parse<'source> for Paren

fn std_parse( input: &mut Parser<'source>, recoverable_errors: &mut Vec<Error>, ) -> Result<Self, Vec<Error>>

Parses a value from the given stream of tokens, advancing the stream past the consumed tokens if parsing is successful.

fn parse(input: &mut Parser<'source>) -> ParseResult<Self>

Parses a value from the given stream of tokens, advancing the stream past the consumed tokens if parsing is successful.

impl PartialEq for Paren

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