Struct luther::Span

pub struct Span<T> { /* fields omitted */ }

Wraps a value with start and end Location's.

Methods

impl<T> Span<T>

pub fn new(start: Location, end: Location, value: T) -> Span<T>

Create a new Span for a given start and end Location and value.

pub fn start(&self) -> Location

Gets the start Location of the Span.

pub fn end(&self) -> Location

Gets the end Location of the Span.

pub fn value_ref(&self) -> &T

Gets a reference to the value of the Span.

pub fn extend(&mut self, end: Location)

Extends the current Span to a new end Location.

pub fn into_inner(self) -> (Location, T, Location)

Consumes the span, returning a (start, value, end) tuple.

This is the format expected for a lalrpop external lexer.

Trait Implementations

impl<T: Clone> Clone for Span<T>

fn clone(&self) -> Span<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: PartialEq> PartialEq for Span<T>

fn eq(&self, __arg_0: &Span<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Span<T>) -> bool

This method tests for !=.

impl<T: Eq> Eq for Span<T>

impl<T: Debug> Debug for Span<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl From<(usize, char)> for Span<char>

fn from((pos, value): (usize, char)) -> Self

Converts from a (pos, value) to a Span.

This conversion is designed to support the Item type of the iterator returned from the str::char_indicies() method. It assumes the pos is the starting position and that the value is encoded in utf8.
