Struct Loop

pub struct Loop {
    pub body: Box<Expr>,
    pub span: Range<usize>,
    pub loop_span: Range<usize>,
}

A loop expression, as in loop { ... }. The code inside the braces is evaluated repeatedly until a break expression is encountered.

Fields

body: Box<Expr>

The body of the loop.

span: Range<usize>

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

loop_span: Range<usize>

The span of the loop keyword.

Implementations

impl Loop

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

Returns the span of the loop expression.

Trait Implementations

impl Clone for Loop

fn clone(&self) -> Loop

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Loop

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

Formats the value using the given formatter.

impl Display for Loop

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

Formats the value using the given formatter.

impl Latex for Loop

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 Loop

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 Loop

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