This package contains a library to parse and analyze V8 heap snapshots. It is published both as a Rust crate and npm package with WebAssembly bindings. It takes as input in the V8 .heapshot format, parses it to a graph structure, and exposes information about that graph.

The APIs exposed by the Rust package and JavaScript package are separate: heap snapshots are very large, and we have optimized the JavaScript bindings for usage in VS Code's visualization tools. However, if there's more information you need from the bindings, please make a pull requeset!
