Struct debris_parser::LocalSpan

pub struct LocalSpan(pub Span);

Wrapper over normal spans, to ensure that parser spans are not accidentally mixed with hir spans

Tuple Fields

0: Span

Methods from Deref<Target = Span>

pub const EMPTY: Span = _

pub fn at_start(&self) -> Span

Returns a span with the same start and a length of one

pub fn start(&self) -> usize

Returns the start of this span

pub fn end(&self) -> usize

Returns the end of this span

pub fn len(&self) -> usize

Returns the length of this span

pub fn is_empty(&self) -> bool

Returns, whether this span is empty

Thanks, clippy.

pub fn until(&self, other: Span) -> Span

Constructs a new span which ranges from the start of this span to the end of the other span

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

pub fn char_bounds(&self, source: &str) -> (usize, usize)

Since ranges are used to index into a str on a byte level, a span starting at index 10 is not necessarily the character at index 10. This methods iterates over the source chars until it finds the character at the byte positions marked by this span. This methods panics if the span is out of bounds.

Returns:

The returned tuple has the shape (start_character_index, end_character_index)

Trait Implementations

impl Clone for LocalSpan

fn clone(&self) -> LocalSpan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LocalSpan

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

Formats the value using the given formatter.

impl Deref for LocalSpan

type Target = Span

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl PartialEq for LocalSpan

fn eq(&self, other: &LocalSpan) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
