Crate plumbob 

FRL link training state machine for HDMI 2.1.

plumbob implements the Fixed Rate Link (FRL) training procedure defined in the HDMI 2.1 specification. It defines the ScdcClient interface its dependencies must satisfy and exposes FrlTrainer as the central entry point.

Features

• alloc — enables TrainingTrace and FrlTrainer::train_at_rate_traced.
• std — implies alloc; no additional API surface.
