Enum ExportTarget 

pub enum ExportTarget {
    DuckDb,
    BigQuery,
    Snowflake,
}

A supported downstream warehouse target. Closed, in-tree, contract-tested set; chosen at runtime from --target X, one per run.

Variants

DuckDb

Reference consumer of Rivet Parquet — honors every native logical type (JSON, UUID, decimal, list) on autoload.

BigQuery

Cloud warehouse. Its Parquet autoloader is weaker than DuckDB’s: see the per-type autoload_type notes in [bigquery].

Snowflake

Cloud warehouse. Like BigQuery, its Parquet autoload degrades JSON, UUID, naive timestamps and TIME — see [snowflake]. Verified live.

Implementations

impl ExportTarget

pub fn parse(s: &str) -> Option<Self>

pub fn valid_target_names() -> &'static str

Human-readable list of every spelling parse accepts, for “unknown target” error messages. Single source so the message can’t drift from parse (it once said “bigquery, duckdb” and missed snowflake). Aliases are shown in parens after each canonical name.

pub fn label(self) -> &'static str

pub fn resolve_column(self, input: TargetInput<'_>) -> TargetColumnSpec

Resolve one already-mapped column against this target.

pub fn resolve_table(self, mappings: &[TypeMapping]) -> Vec<TargetColumnSpec>

Resolve a whole table’s worth of columns, one spec per column in order. Consumed today by the type-report’s recovery-SQL emission (preflight::type_report); plan-load (ADR-0014 Phase B) would be a second consumer.

pub fn recovery_sql( self, specs: &[TargetColumnSpec], table: &str, ) -> Option<String>

SQL that recovers target-native types after a bare autoload degraded them (ADR-0014 L5). For BigQuery this is a CREATE TABLE … AS SELECT over the autoloaded staging table applying per-column casts — BigQuery’s Parquet loader will NOT coerce a declared native type on load (verified against live BQ: BYTES→JSON, TIMESTAMP→DATETIME loads are rejected), so the recovery has to be a post-load transform, not a load schema. None when the target reads the interchange Parquet faithfully (DuckDB).

Trait Implementations

impl Clone for ExportTarget

fn clone(&self) -> ExportTarget

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ExportTarget

impl Debug for ExportTarget

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ExportTarget

impl PartialEq for ExportTarget

fn eq(&self, other: &ExportTarget) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
