Struct QueryDataset 

pub struct QueryDataset {
    pub default: Vec<NamedNode>,
    pub named: Option<Vec<NamedNode>>,
}

A SPARQL query dataset specification.

Fields

default: Vec<NamedNode>

Default graphs (FROM clauses)

named: Option<Vec<NamedNode>>

Named graphs (FROM NAMED clauses)

Implementations

impl QueryDataset

pub fn new() -> Self

Creates a new empty dataset

pub fn with_default_graphs(graphs: Vec<NamedNode>) -> Self

Creates a dataset with default graphs

pub fn with_named_graphs(graphs: Vec<NamedNode>) -> Self

Creates a dataset with named graphs

pub fn add_default_graph(&mut self, graph: NamedNode)

Adds a default graph

pub fn add_named_graph(&mut self, graph: NamedNode)

Adds a named graph

pub fn is_empty(&self) -> bool

Returns true if the dataset is empty

pub fn fmt_sse(&self, f: &mut impl Write) -> Result

Formats using the SPARQL S-Expression syntax

Trait Implementations

impl Clone for QueryDataset

fn clone(&self) -> QueryDataset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryDataset

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

Formats the value using the given formatter.

impl Default for QueryDataset

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QueryDataset

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for QueryDataset

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

Formats the value using the given formatter.

impl Hash for QueryDataset

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for QueryDataset

fn eq(&self, other: &QueryDataset) -> 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.

impl Serialize for QueryDataset

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for QueryDataset
