source-map's Introduction

Source map

Utilities for building source maps (v3), handling source location representations and source files.

Includes

SpanWithSource, a structure which represents a section of a specific source
SpanWithoutSource, a structure which represents a general section without a specific source
SourceId, a identifier for a source file
StringWithOptionalSourceMap, along with the ToString trait makes generating string representations with and adding source markings trivial
A lsp-types-morphisms feature which allows conversion of position type to lsp-types
The MapFileStore struct and the FileSystem trait for storing source files and other information
Utilities for turning byte indices into line and column information

source-map's Issues

Latest source-map breaks enzo_parser

If I just add enzo crate to a project I get a bunch of errors. I had to pin the version of source-map to get the build to work.

error[E0433]: failed to resolve: could not find `StringWithSourceMap` in `source_map`
