Struct rustc_utils::source_map::range::CharRange

pub struct CharRange {
    pub start: CharPos,
    pub end: CharPos,
    pub filename: FilenameIndex,
}

Data structure for sharing spans outside rustc.

Rustc uses byte indexes to describe ranges of source code, whereas most Javascript-based editors I’ve encountered (e.g. VSCode) use character-based (really grapheme-based) indexes. This data structure along with ByteRange helps convert between the two representations.

Fields

start: CharPos

end: CharPos

filename: FilenameIndex

Implementations

impl CharRange

pub fn from_span(span: Span, source_map: &SourceMap) -> Result<Self>

Trait Implementations

impl Clone for CharRange

fn clone(&self) -> CharRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CharRange

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

Formats the value using the given formatter.

impl Hash for CharRange

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 CharRange

fn eq(&self, other: &CharRange) -> 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 Serialize for CharRange

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSpan for CharRange

fn to_span(&self, tcx: TyCtxt<'_>) -> Result<Span>

impl Copy for CharRange

impl Eq for CharRange

impl StructuralEq for CharRange

impl StructuralPartialEq for CharRange
