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 TS for CharRange

const EXPORT_TO: Option<&'static str> = _

fn decl() -> String

Declaration of this type, e.g. interface User { user_id: number, ... }. This function will panic if the type has no declaration.

fn name() -> String

Name of this type in TypeScript.

fn inline() -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened() -> String

Flatten an type declaration.
This function will panic if the type cannot be flattened.

fn dependencies() -> Vec<Dependency>

where Self: 'static,

Information about types this type depends on. This is used for resolving imports when exporting to a file.

fn transparent() -> bool

true if this is a transparent type, e.g tuples or a list.
This is used for resolving imports when using the export! macro.

fn name_with_type_args(args: Vec<String>) -> String

Name of this type in TypeScript, with type arguments.

fn export() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to a file. The output file can be specified by annotating the type with #[ts(export_to = ".."]. By default, the filename will be derived from the types name.

fn export_to(path: impl AsRef<Path>) -> Result<(), ExportError>

where Self: 'static,

Manually export this type to a file with a file with the specified path. This function will ignore the #[ts(export_to = "..)] attribute.

fn export_to_string() -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String.
This function does not format the output, even if the format feature is enabled.

impl ToSpan for CharRange

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

impl Copy for CharRange

impl Eq for CharRange
