Expand description

Serialize the given data structure as pretty-printed JSON into the I/O stream.

Serialization guarantees it only feeds valid UTF-8 sequences to the writer.

Errors

Serialization can fail if T’s implementation of Serialize decides to fail, or if T contains a map with non-string keys.
