Enum Constant Summary

Enum Constants

Enum Constant	Description
OVER_SPECIFIED	The reason a coder could not be provided is because the type variable T is over specified with multiple incompatible coders.
TYPE_ERASURE	The reason a coder could not be provided is type erasure, for example when requesting coder inference for a List<T> where T is unknown.
UNKNOWN	The reason a coder could not be provided is unknown or does not have an established CannotProvideCoderException.ReasonCode.
