Module json 

Data conversion between greptime’s StructType and Json

The idea of this module is to provide utilities to convert serde_json::Value to greptime’s StructType and vice versa.

The struct will carry all the fields of the Json object. We will not flatten any json object in this implementation.

Structs

JsonContext

Context for JSON encoding/decoding that tracks the current key path

Enums

JsonStructureSettings

The configuration of JSON encoding
