pub struct Span(pub usize, pub usize);

Normal byte offset span

Tuple Fields

0: usize

1: usize

Implementations

impl Span

pub fn length(&self) -> usize

Length of the span in bytes

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl DecodeSpan<LineSpan> for Span

Available on crate feature line-numbers only.

fn decode_span(span: &LineSpan, _: &mut Context<LineSpan>) -> Self

Decode span

impl Display for Span

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

Formats the value using the given formatter.

impl From<Range<usize>> for Span

fn from(r: Range<usize>) -> Span

Converts to this type from the input type.

impl Into<SourceSpan> for Span

fn into(self) -> ErrorSpan

Converts this type into the (usually inferred) input type.

impl PartialEq for Span

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

impl Span for Span

type Context = ()

Extra context used in a span.

type Offset = usize

A type representing a span’s start or end offset from the start of the input.

fn new(_context: (), range: Range<usize>) -> Self

Create a new span given a context and an offset range.

fn context(&self)

Return the span’s context.

fn start(&self) -> usize

Return the start offset of the span.

fn end(&self) -> usize

Return the end offset of the span.
