Struct wasccgraph_common::ResultSet

pub struct ResultSet {
    pub columns: Vec<Column>,
    pub statistics: Statistics,
}

Represents the return data from a graph. You shouldn't have to use this type directly, but rather extract rows and columns via vectors of tuples and pattern matching/destructing

Fields

columns: Vec<Column>

The columns of this result set.

Empty if the response did not contain any return values.

statistics: Statistics

Contains statistics messages from the response.

Implementations

impl ResultSet

pub fn num_columns(&self) -> usize

Returns the number of rows in the result set.

pub fn num_rows(&self) -> usize

Returns the number of columns in the result set.

pub fn get_scalar(
    &self,
    row_idx: usize,
    column_idx: usize
) -> GraphResult<&Scalar>

Returns the scalar at the given position.

Returns an error if the value at the given position is not a scalar or if the position is out of bounds.

pub fn get_node(&self, row_idx: usize, column_idx: usize) -> GraphResult<&Node>

Returns the node at the given position.

Returns an error if the value at the given position is not a node or if the position is out of bounds.

pub fn get_relation(
    &self,
    row_idx: usize,
    column_idx: usize
) -> GraphResult<&Relation>

Returns the relation at the given position.

Returns an error if the value at the given position is not a relation or if the position is out of bounds.

Trait Implementations

impl Clone for ResultSet

fn clone(&self) -> ResultSet

Returns a copy of the value.

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