Struct ProjectedRow 

pub struct ProjectedRow<E: EntityKind> { /* private fields */ }

ProjectedRow

One scalar projection output row emitted in planner declaration order. values carries evaluated expression outputs for this row.

Implementations

impl<E: EntityKind> ProjectedRow<E>

pub const fn new(id: Id<E>, values: Vec<Value>) -> Self

Construct one projected scalar row.

pub const fn id(&self) -> Id<E>

Borrow the source row identifier.

pub const fn values(&self) -> &[Value]

Borrow projected scalar values in declaration order.

pub fn into_parts(self) -> (Id<E>, Vec<Value>)

Consume and return (id, projected_values).

Trait Implementations

impl<E: Clone + EntityKind> Clone for ProjectedRow<E>

fn clone(&self) -> ProjectedRow<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug + EntityKind> Debug for ProjectedRow<E>

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

Formats the value using the given formatter.

impl<E: PartialEq + EntityKind> PartialEq for ProjectedRow<E>

fn eq(&self, other: &ProjectedRow<E>) -> 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.
