Encodes the specified value.

Encodes the specified value.

Concrete methods

def contramap[DD](f: DD => D): Encoder[E, DD, T]

Creates a new Encoder instances that applies the specified function before encoding.

Creates a new Encoder instances that applies the specified function before encoding.

This is a convenient way of creating Encoder instances: if you already have an Encoder[E, D, R], need to write an Encoder[E, DD, R] and know how to turn a DD into a D, you need but call contramap.
