Trait Implementations

impl Clone for Span

fn clone(&self) -> Self

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 Display for Span

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

Formats the value using the given formatter.

impl Eq for Span

impl From<&Span> for Span

fn from(span: &Self) -> Self

Converts to this type from the input type.

impl Hash for Span

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Span

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

Equality operator ==.

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

Inequality operator !=.

impl Span for Span

type SourceId = Source

The identifier used to uniquely refer to a source. In most cases, this is the fully-qualified path of the file.

fn end(&self) -> usize

Get the (exclusive) end offset of this span.

fn source(&self) -> &Source

Get the identifier of the source that this span refers to.

fn start(&self) -> usize

Get the start offset of this span.

fn len(&self) -> usize

Get the length of this span (difference between the start of the span and the end of the span).

fn is_empty(&self) -> bool

Returns true if this span has length zero.

fn contains(&self, offset: usize) -> bool

Determine whether the span contains the given offset.

impl Span for Span

type Context = Source

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 context(&self) -> Source

Return the span’s context.

fn end(&self) -> usize

Return the end offset of the span.

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

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

fn start(&self) -> usize

Return the start offset of the span.

fn to_end(&self) -> Self

where Self: Sized,

Turn this span into a zero-width span that starts and ends at the end of the original.

fn union(&self, other: Self) -> Self

where Self::Context: PartialEq + Debug, Self::Offset: Ord, Self: Sized,

Combine two assumed-contiguous spans together into a larger span that encompasses both (and anything between).
