Struct ra_ap_span::SpanMap

pub struct SpanMap<S> { /* private fields */ }

Maps absolute text ranges for the corresponding file to the relevant span data.

Implementations

impl<S: Copy> SpanMap<S>

pub fn empty() -> Self

Creates a new empty SpanMap.

pub fn finish(&mut self)

Finalizes the SpanMap, shrinking its backing storage and validating that the offsets are in order.

pub fn push(&mut self, offset: TextSize, span: S)

Pushes a new span onto the SpanMap.

pub fn ranges_with_span(&self, span: S) -> impl Iterator<Item = TextRange> + '_

where S: Eq,

Returns all TextRanges that correspond to the given span.

Note this does a linear search through the entire backing vector.

pub fn span_at(&self, offset: TextSize) -> S

Returns the span at the given position.

pub fn spans_for_range(&self, range: TextRange) -> impl Iterator<Item = S> + '_

Returns the spans associated with the given range. In other words, this will return all spans that correspond to all offsets within the given range.

pub fn iter(&self) -> impl Iterator<Item = (TextSize, S)> + '_

Trait Implementations

impl<S: Clone> Clone for SpanMap<S>

fn clone(&self) -> SpanMap<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for SpanMap<S>

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

Formats the value using the given formatter.

impl<S: Hash> Hash for SpanMap<S>

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<S: PartialEq> PartialEq for SpanMap<S>

fn eq(&self, other: &SpanMap<S>) -> 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.
