I was pointed to another implementation in Fuchsia's Future eXperience tool suite:
https://cs.opensource.google/fuchsia/fuchsia/+/main:src/developer/ffx/lib/fastboot/interface/src/fastboot_interface.rs
https://cs.opensource.google/fuchsia/fuchsia/+/main:src/developer/ffx/lib/usb_fastboot_discovery/src/lib.rs
