#
Format

pub(all) enum Format {
  Text
  Binary
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

Data format for a PostgreSQL cell or parameter.

Text (format code 0) — human-readable representation. Binary (format code 1) — compact wire-protocol representation.

#
Value

source

pub(all) enum Value {
  Null
  Bool(Bool)
  Int(Int)
  Int64(Int64)
  Float(Double)
  String(String)
  Bytes(Bytes)
  Timestamp(Int64)
  Json(Json)
  Array(Array[Value])
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

PostgreSQL value type used for encoding (client → server via ToValue) and decoding (server → client via FromValue).

Variants map to PostgreSQL types as follows:

Variant	PG types
Null	SQL NULL
Bool	bool (16)
Int	int2 (21), int4 (23)
Int64	int8 (20)
Float	float4 (700), float8 (701)
String	text, varchar, bpchar, name, uuid, …
Bytes	bytea (17)
Timestamp(Int64)	timestamp (1114), timestamptz (1184)
Json(Json)	json (114), jsonb (3802)
