Struct OwnedPhysicalRow 

pub struct OwnedPhysicalRow {
    pub schema: RowSchema,
    pub row: PhysicalRow,
}

Owned schema/row pair for row-at-a-time consumers that must outlive a decoded batch. Cloning this carrier shares the immutable schema index and row fragments; it does not build a named row or clone contained values.

Fields

schema: RowSchema

row: PhysicalRow

Implementations

impl OwnedPhysicalRow

pub fn new(schema: RowSchema, row: PhysicalRow) -> Self

pub fn view(&self) -> PhysicalRowView<'_>

pub fn get(&self, name: &str) -> Option<&Value>

pub fn relabel(self, schema: RowSchema) -> ExecResult<Self>

Apply a new logical schema by position while sharing the existing value fragments. Relation aliases and derived-column names therefore do not require an intermediate named row.

pub fn into_result_row(self) -> ResultRow

Trait Implementations

impl Clone for OwnedPhysicalRow

fn clone(&self) -> OwnedPhysicalRow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OwnedPhysicalRow

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

Formats the value using the given formatter.

impl PartialEq for OwnedPhysicalRow

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

Equality operator ==.

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

Inequality operator !=.

impl RowLookup for OwnedPhysicalRow

fn column(&self, name: &str) -> Option<&Value>

fn column_is_ambiguous(&self, name: &str) -> bool

Whether an unqualified name identifies more than one visible input column. Callers must report SQLSTATE 42702 instead of selecting an arbitrary suffix match.

fn qualified_column(&self, qualifier: &str, column: &str) -> Option<&Value>

fn qualified_column_is_ambiguous(&self, qualifier: &str, column: &str) -> bool

Whether a qualified identity names more than one visible input column.

fn positional_column(&self, index: usize) -> Option<&Value>

Return a value by the physical schema position used to construct this row view. Materialized named rows do not expose positional access; projected execution sources override it so compiled hot paths can avoid repeating string lookup for every expression and row.

fn visit_columns(&self, visitor: &mut dyn FnMut(&str, &Value))

Visit every logical column in schema order. Named rows use their map order; positional execution rows override this without materializing a map. The default keeps narrow projected lookup implementations source compatible when they deliberately do not expose whole-row semantics.
