Source Map Cache

Manages source files for a compiler, providing mapping between file IDs, paths, and source locations (line/column).

Overview

This crate provides the SourceMap struct, which is responsible for:

Mounting Directories: Associates symbolic names ("mounts") with file system directories containing source code.
Reading & Caching: Reads source files either by absolute path or relative to a mount point, caching their contents and metadata.
File IDs: Assigns a unique FileId (u16) to each loaded file.
Location Mapping: Efficiently converts byte offsets within a file (often obtained from parsers or lexers using crates like source-map-node) into human-readable line and column numbers.
Source Snippets: Retrieves the source text corresponding to a given span (file ID, offset, length).

Add this to your Cargo.toml:

[dependencies]
source-map-cache = "0.0.2"
