Struct CodeMap 

pub struct CodeMap { /* private fields */ }

The code map contains the original source and can map VM instructions to text ranges inside that source.

Implementations

impl CodeMap

pub fn new(text: impl Into<String>) -> CodeMap

Create a new, empty CodeMap from a text and a set of ranges.

pub fn text(&self) -> &str

Get the original source code.

pub fn map_instruction( &mut self, instruction: usize, span: Span, ) -> Result<(), RangeError>

Add new mapping starting at instruction which maps to span.

pub fn span_from_instruction( &self, ip: usize, ) -> Result<SpannedText<'_>, RangeError>

Retrieve the Span containing the given instruction pointer.

Trait Implementations

impl Archive for CodeMap

where String: Archive, Vec<(usize, Span)>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<CodeMap>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedCodeMap

The archived representation of this type.

type Resolver = CodeMapResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <CodeMap as Archive>::Resolver, out: Place<<CodeMap as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for CodeMap

fn clone(&self) -> CodeMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodeMap

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CodeMap

fn deserialize<__D>( __deserializer: __D, ) -> Result<CodeMap, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<CodeMap, __D> for <CodeMap as Archive>::Archived

where __D: Fallible + ?Sized, String: Archive, <String as Archive>::Archived: Deserialize<String, __D>, Vec<(usize, Span)>: Archive, <Vec<(usize, Span)> as Archive>::Archived: Deserialize<Vec<(usize, Span)>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<CodeMap, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for CodeMap

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

impl<__S> Serialize<__S> for CodeMap

where __S: Fallible + ?Sized, String: Serialize<__S>, Vec<(usize, Span)>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<CodeMap as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for CodeMap

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.
