kantan.codecs.export

package kantan.codecs.export

Provides a simple mechanism to insert derived type class instances in the implicit resolution mechanism.

By default, when imported, such instances have the highest possible priority, which is typically problematic with shapeless instance derivation: bespoke instances for Option or Either, for example, find themselves shadowed by the generically derived ones.

If such instances are of type kantan.codecs.export.DerivedDecoder / kantan.codecs.export.DerivedEncoder rather than Decoder / Encoder, however, they'll find themselves with a lower precedence and only be used if no other, more specific instance is found.
