Struct QueryResult 

pub struct QueryResult { /* private fields */ }

A query result: the boundary Edn value plus its ResultShape, with typed accessors keyed to the shape.

Implementations

impl QueryResult

pub fn new(shape: ResultShape, value: Edn) -> Self

Wraps a boundary result value with its shape.

pub fn shape(&self) -> ResultShape

The result shape.

pub fn edn(&self) -> &Edn

The raw boundary Edn value.

pub fn into_edn(self) -> Edn

Consumes the result, yielding the raw boundary Edn value.

pub fn rows(&self) -> Vec<Row<'_>>

Rows of a relation result. Empty for other shapes.

pub fn values(&self) -> Vec<&Edn>

Values of a collection result. Empty for other shapes.

pub fn values_as<T: FromEdn>(&self) -> Result<Vec<T>, ClientError>

Typed values of a collection result.

Errors

Returns ClientError::Decode if any value is not of type T.

pub fn tuple(&self) -> Option<Row<'_>>

The single tuple of a tuple result, or None when empty.

pub fn scalar(&self) -> Option<&Edn>

The single value of a scalar result, or None when empty (nil).

pub fn scalar_as<T: FromEdn>(&self) -> Result<Option<T>, ClientError>

The typed scalar value of a scalar result.

Errors

Returns ClientError::Decode if the value is not of type T.

pub fn is_empty(&self) -> bool

Whether the result is empty (no rows/values, or a nil tuple/scalar).

Trait Implementations

impl Clone for QueryResult

fn clone(&self) -> QueryResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryResult

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

Formats the value using the given formatter.
