Module convert 

Type-aware conversion from BigQuery TableRows to JSON objects.

BigQuery returns every scalar cell as a string regardless of declared type, with non-trivial structure (RECORD/STRUCT/REPEATED) reflected in nested cell shapes:

• A RECORD cell carries {"f": [...nested cells...]} in its value field.
• A REPEATED cell carries [{"v": ...cell...}, ...] in its value field — one element per array entry.

This module walks the schema in lockstep with each row’s cells and emits a serde_json::Value::Object keyed by column name, with each cell typed according to its TableFieldSchema.

Type mapping

BigQuery type	JSON output
INTEGER / INT64	Number (i64 if it fits, else f64)
FLOAT / FLOAT64	Number (f64)
NUMERIC / BIGNUMERIC	String (full precision preserved)
BOOLEAN / BOOL	Bool
RECORD / STRUCT	nested Object
REPEATED <T> mode	Array<T>
JSON	parsed Value (falls back to String)
STRING / BYTES / TIMESTAMP / DATE / TIME / DATETIME / GEOGRAPHY / INTERVAL	String
NULL cell	Null
