Implementations

impl Span

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

Returns whether the end of self is the start of other

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

Returns a new Span which starts at the start of self a ends at the end of other

pub fn get_start(&self) -> Position

pub fn get_end(&self) -> Position

pub fn into_line_column_span<T>(self, fs: &impl FileSystem) -> LineColumnSpan<T>where T: StringEncoding,

pub const NULL_SPAN: Span = Span{ start: 0, end: 0, source: SourceId::NULL,}

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl PartialEq<Span> for Span

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

impl SelfRustTokenize for Span

fn append_to_token_stream(&self, token_stream: &mut TokenStream)

fn to_tokens(&self) -> TokenStream

Returns the tokens used to construct self

impl Serialize for Span

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Visitable for Span

fn visit<TData>( &self, _visitors: &mut (impl VisitorReceiver<TData> + ?Sized), _data: &mut TData, _settings: &VisitSettings, _chain: &mut Annex<'_, Chain> )

fn visit_mut<TData>( &mut self, _visitors: &mut (impl VisitorMutReceiver<TData> + ?Sized), _data: &mut TData, _settings: &VisitSettings, _chain: &mut Annex<'_, Chain> )
