Expand description

A note about error handling.

Encoders may be fallible, but in practice failure is rare and there are so many nested calls that typical Rust error handling (via Result and ?) is pervasive and has non-trivial cost. Instead, impls of this trait must implement a delayed error handling strategy. If a failure occurs, they should record this internally, and all subsequent encoding operations can be processed or ignored, whichever is appropriate. Then they should provide a finish method that finishes up encoding. If the encoder is fallible, finish should return a Result that indicates success or failure.
