NewDecoder creates a new decoder instance.

NewStreamDecoder adapts to encoding/json.NewDecoder API.

Pretouch compiles vt ahead-of-time to avoid JIT compilation on-the-fly, in order to reduce the first-hit latency.

Skip skips only one json value, and returns first non-blank character position and its ending position if it is valid.

Decoder is the decoder context object.

StreamDecoder is the decoder context object for streaming input.
