class Dry::Schema::KeyMap

@api public
Instances of this class are used as the very first step by the schema processors.
to rebuild an input hash using configured coercer function.
KeyMap objects expose an API for introspecting schema keys and the ability
Represents a list of keys defined by the DSL
