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 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 Debug for ExportTarget

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

Formats the value using the given formatter.

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.
