Struct PhysicalRowView 

pub struct PhysicalRowView<'a> { /* private fields */ }

Stack-only schema/row pair implementing the scalar evaluator’s read seam.

Implementations

impl<'a> PhysicalRowView<'a>

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

pub fn value_at(&self, logical: usize) -> Option<&'a Value>

pub fn iter(&'a self) -> impl Iterator<Item = (&'a str, &'a Value)> + 'a

pub fn to_result_row(&self) -> ResultRow

Trait Implementations

impl<'a> Clone for PhysicalRowView<'a>

fn clone(&self) -> PhysicalRowView<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for PhysicalRowView<'a>

impl<'a> Debug for PhysicalRowView<'a>

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

Formats the value using the given formatter.

impl RowLookup for PhysicalRowView<'_>

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.
