Psych::Coder

If an object defines encode_with, then an instance of Psych::Coder will be passed to the method when the object is being serialized. The Coder automatically assumes a Psych::Nodes::Mapping is being emitted. Other objects like Sequence and Scalar may be emitted if seq= or scalar= are called, respectively.

Attributes

implicit[RW]
object[RW]
seq[R]
style[RW]
