Enum JoinMode 

pub enum JoinMode {
    None,
    FkBitmap,
    DataFusionHash,
}

Which join execution path served a query (Priority 13: join diagnostics). None for non-join queries.

Variants

None

No join in the query (or the join path was never reached).

FkBitmap

Native FK↔PK roaring-bitmap intersection — no hash-join materialization (crate::engine::Table index resolve only).

DataFusionHash

Fell back to DataFusion’s hash join (shape the native path can’t serve).

Trait Implementations

impl Clone for JoinMode

fn clone(&self) -> JoinMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JoinMode

impl Debug for JoinMode

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

Formats the value using the given formatter.

impl Default for JoinMode

fn default() -> JoinMode

Returns the “default value” for a type.

impl Display for JoinMode

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

Formats the value using the given formatter.

impl Eq for JoinMode

impl PartialEq for JoinMode

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