Library that provided embedded-hal implementations for benchmarking transfer performance for drivers.
This crate is still very experimental. The API, in particular the serialization/display aspect will probably change a lot.
Drivers such as ST7789 can gauge performance on host platforms by counting transfers over SPI, I2C or other embedded-hal abstracted interfaces.
Use the provided structures in stead of real abstractions with your driver implementation to get byte, call and delay counts of your driver given a specific operation.
