Standard logical types that package configs may declare.

All string aliases accepted in JSON are normalised to one of these variants by parse_canonical. Unknown strings fall through to CanonicalType::Custom so that existing packages using raw SQL type names continue to work unchanged.

Variants

Text

Unbounded unicode text (TEXT / VARCHAR without limit).

Varchar(Option<u32>)

Variable-length text with optional length cap.

Char(Option<u32>)

Fixed-length text.

SmallInt

16-bit integer.

Int

32-bit integer.

BigInt

64-bit integer.

Real

32-bit floating point.

Double

64-bit floating point (default for "float").

Decimal(Option<(u8, u8)>)

Fixed-precision decimal. Params: (precision, scale).

Boolean

Boolean true/false.

Uuid

UUID (128-bit universally unique identifier).

Json

JSON document. Dialects may use a richer binary form (e.g. JSONB in Postgres).

Jsonb

Explicitly request the binary JSON form where available; degrades to JSON/TEXT elsewhere.

Timestamp

Timestamp with time zone. Always stores timezone information.

TimestampNtz

Timestamp without time zone (use sparingly — prefer CanonicalType::Timestamp).

Date

Calendar date (no time component).

Time

Time of day without time zone.

Timetz

Time of day with time zone.

Bytes

Binary data.

Serial

Auto-incrementing 32-bit integer primary key.

BigSerial

Auto-incrementing 64-bit integer primary key.

Asset

SDK pseudo-type: a single asset stored as a relative path string.

AssetArray

SDK pseudo-type: a list of assets stored as a JSON array of path strings.

Array(Box<CanonicalType>)

Typed array of another canonical type (e.g. text[], uuid[]).

Custom(String)

Pass-through for schema-qualified enums (e.g. "myschema.status") and any raw SQL type string not matched by the canonical parser. Rendered verbatim in DDL.

Trait Implementations
