The Beginnings of a high-performance, low memory footprint VCD Viewer in Rust for massive multi-GB waveforms

very fast
loads 400MB of VCD waveform per second on an 8 core 2017 desktop CPU with NVMe storage
consumes roughly between 10 - 50MB of memory per GB of waveform

elegant/pretty UI
can be easily ported to work in browser via webassembly
allows high-performance custom Rust plugins to manipulate and generate new waveforms live

Make sure you have a test vcd file to get you started. You can grab a large VCD file from here.

The first build of the program may take some time.

cargo run --release test-vcd-files/aldec/SPI_Write.vcd

You can run all the tests with cargo test

support multiple root scopes
support parsing dates with commas
Fix warning especially usage and restriction warnings once I'm able to successfully parse all sample VCDs.
Consolidate error messages and add cursors throughout.
Consider what to do with don't care values will probably just convert them to strings for now.
Include line and possible column numbers
Take a look at GTKWave parser to compare effificiency.
