Struct LitUnit

pub struct LitUnit {
    pub span: Range<usize>,
}

The unit type, written as (). The unit type is by-default returned by functions that do not return a value.

Fields

span: Range<usize>

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

Trait Implementations

impl Clone for LitUnit

fn clone(&self) -> LitUnit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LitUnit

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

Formats the value using the given formatter.

impl Display for LitUnit

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

Formats the value using the given formatter.

impl Latex for LitUnit

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 LitUnit

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 LitUnit

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