Struct Solutions 

pub struct Solutions {
    pub variables: Vec<String>,
    pub rows: Vec<Vec<Option<Term>>>,
}

A table of SPARQL solutions: variable names in projection order and rows of optional terms (None is unbound).

Fields

variables: Vec<String>

The variable names, without ?.

rows: Vec<Vec<Option<Term>>>

The rows, each parallel to variables.

Implementations

impl Solutions

pub fn column(&self, var: &str) -> Option<usize>

The column of variable var.

pub fn get(&self, row: usize, var: &str) -> Option<&Term>

The value of var in row row, if bound.

pub fn values(&self, var: &str) -> Vec<Term>

Every bound value of var, in row order.

pub fn len(&self) -> usize

The number of rows.

pub fn is_empty(&self) -> bool

True when there are no rows.
