Enum DryRunScanSummaryMode 

pub enum DryRunScanSummaryMode {
    MetadataOnly,
    ExhaustScanMetadata,
}

Controls how much source scan metadata a dry-run report should collect.

This only affects dry-run source reporting. It does not allow row production, SQL Server lifecycle work, bulk writer construction, or writes.

Variants

MetadataOnly

Use source metadata already available from normal dry-run output planning.

This is the cheaper default. It avoids DataFusion physical scan planning and reports source file counts as unavailable for cost avoidance.

ExhaustScanMetadata

Run DataFusion physical scan planning to collect provider scan stats.

This may perform extra table metadata work so dry-run reports can expose provider stats and exact or estimated source file counts. It still stops before producing rows.

Implementations

impl DryRunScanSummaryMode

pub const fn as_str(self) -> &'static str

Returns a stable lower-snake-case code for report serialization.

Trait Implementations

impl Clone for DryRunScanSummaryMode

fn clone(&self) -> DryRunScanSummaryMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DryRunScanSummaryMode

impl Debug for DryRunScanSummaryMode

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

Formats the value using the given formatter.

impl Default for DryRunScanSummaryMode

fn default() -> DryRunScanSummaryMode

Returns the “default value” for a type.

impl Display for DryRunScanSummaryMode

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

Formats the value using the given formatter.

impl Eq for DryRunScanSummaryMode

impl PartialEq for DryRunScanSummaryMode

fn eq(&self, other: &DryRunScanSummaryMode) -> 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.
