Crate faucet_common_spanner 

Shared Google Cloud Spanner types for the faucet-stream ecosystem.

This crate holds everything the faucet-source-spanner and faucet-sink-spanner connectors have in common:

• SpannerCredentials — the { type, config } credentials enum shared by both connectors (mirrors faucet-common-bigquery).
• SpannerConnection — the flattened connection block (project_id / instance / database / auth / max_sessions / emulator_host) plus SpannerConnection::connect / SpannerConnection::connect_admin client builders.
• types — INFORMATION_SCHEMA type-string parsing and the mapping to JSON-Schema fragments.
• decode — generic Spanner row → serde_json::Value decoding for arbitrary queries (no compile-time schema).
• encode — serde_json::Value → Spanner mutation value encoding keyed by the destination column type.

Modules

decode

Generic Spanner row → serde_json::Value decoding.

encode

serde_json::Value → Spanner mutation value encoding.

types

Spanner INFORMATION_SCHEMA type-string parsing and the mapping from Spanner column types to JSON-Schema fragments.

Structs

SpannerConnection

Connection block shared by the Spanner source and sink configs (flattened into each connector config via #[serde(flatten)]).

Enums

SpannerCredentials

Credentials used to authenticate against Cloud Spanner.

Functions

quote_ident_spanner

Quote a Spanner identifier with backticks, doubling any embedded backtick. Spanner uses GoogleSQL backtick quoting (like BigQuery/MySQL).
