Struct CuvsLogicalNode 

pub struct CuvsLogicalNode { /* private fields */ }

DataFusion logical extension for a statically validated cuVS relation call.

Input schemas and options determine its output schema before GPU execution.

Implementations

impl CuvsLogicalNode

pub fn try_new( operation: CuvsOperation, inputs: Vec<LogicalPlan>, options_json: &str, ) -> DataFusionResult<Self>

Validates relation count, option JSON, input schemas, and known cardinalities.

Inputs follow the operation descriptor’s relation-role order. Invalid options, missing columns, unsupported types, or incompatible cardinalities return typed Algeon errors through the DataFusion error boundary.

pub fn operation(&self) -> CuvsOperation

Returns the registered operation represented by this logical node.

pub fn validated_options(&self) -> &CuvsValidatedOptions

Borrows options parsed and validated during node construction.

pub fn output_schema(&self) -> SchemaRef

Returns the Arrow result schema established by call validation.

Trait Implementations

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

fn necessary_children_exprs( &self, _output_columns: &[usize], ) -> Option<Vec<Vec<usize>>>

Returns the necessary input columns for this node required to compute the columns in the output schema
