Creates a Map result with an empty key and value.

fn emit_if(&self, condition: bool) -> Result<Mappings<(), ()>, Error>

Creates a Map result with an empty key and value if condition is true.

fn emit_key<K>(&self, key: K) -> Result<Mappings<K, ()>, Error>

Creates a Map result with a key and an empty value.

fn emit_value<Value>(&self, value: Value) -> Result<Mappings<(), Value>, Error>

Creates a Map result with value and an empty key.
