Type Alias Span

pub type Span = SpanData<SyntaxContext>;

Aliased Type

struct Span {
    pub range: TextRange,
    pub anchor: SpanAnchor,
    pub ctx: SyntaxContext,
}

Fields

range: TextRange

The text range of this span, relative to the anchor. We need the anchor for incrementality, as storing absolute ranges will require recomputation on every change in a file at all times.

anchor: SpanAnchor

The anchor this span is relative to.

ctx: SyntaxContext

The syntax context of the span.

Implementations

Trait Implementations

impl Display for Span

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

Formats the value using the given formatter.

impl<Ctx: Clone> Clone for SpanData<Ctx>

fn clone(&self) -> SpanData<Ctx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Ctx: Debug> Debug for SpanData<Ctx>

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

Formats the value using the given formatter.

impl<Ctx: Hash> Hash for SpanData<Ctx>

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<Ctx: PartialEq> PartialEq for SpanData<Ctx>

fn eq(&self, other: &SpanData<Ctx>) -> 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.
