WireType

Enum WireType 

Source
#[non_exhaustive]
pub enum WireType {
Show 14 variants Bool, Int, Real, Text, Bytes, Uuid, Decimal, Timestamp, TimestampTz, Date, Time, Interval, Json, Jsonb,
}
Expand description

Semantic column type used to select a decoder, independent of any wire source’s native type identity.

The schema side declares one of these per column (via WireColumnTypes) and TypeMap dispatches on it. This replaces the older per-source native key (Oid for pg_walstream, type-name strings for wal2json and maxwell): a single catalog carrying semantic types now drives every source without a per-source translation table.

The set covers every decoder the crate ships. Json and Jsonb stay distinct so a downstream that treats them differently can register different decoders. Decoder policy variants (for example UuidText36Decoder versus UuidBlob16Decoder, or JsonVerbatimDecoder versus JsonCanonicalDecoder) are chosen at registration under the one semantic key, not by adding more keys.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Int

§

Real

Floating-point.

§

Text

UTF-8 text.

§

Bytes

Raw bytes.

§

Uuid

UUID.

§

Decimal

Arbitrary-precision decimal / numeric.

§

Timestamp

Timestamp without time zone.

§

TimestampTz

Timestamp with time zone.

§

Date

Calendar date.

§

Time

Time of day.

§

Interval

Interval / duration.

§

Json

JSON.
