Module encode 

Available on crate features sink-spanner or source-spanner only.

serde_json::Value → Spanner mutation value encoding.

The sink writes arbitrary JSON records, so values are encoded against the destination column type (read once from INFORMATION_SCHEMA). Mutations only carry prost_types::value::Kinds — Spanner infers the type from the table schema — so the object-safe ToKind wrapper EncodedKind is all the mutation builders need.

Structs

EncodedKind

A pre-encoded mutation value. get_type reports STRING but is never consulted on the mutation path (mutations infer types server-side from the table schema); this wrapper must not be used for statement params.

Functions

encode_to_kind

Encode one JSON value for a destination column of type ty.
