Struct Update

pub struct Update { /* private fields */ }

A parsed SPARQL update.

use oxigraph::sparql::Update;

let update_str = "CLEAR ALL ;";
let update = Update::parse(update_str, None)?;

assert_eq!(update.to_string().trim(), update_str);

Implementations

impl Update

pub fn parse( update: &str, base_iri: Option<&str>, ) -> Result<Self, SparqlSyntaxError>

Parses a SPARQL update with an optional base IRI to resolve relative IRIs in the query.

pub fn using_datasets(&self) -> impl Iterator<Item = &QueryDataset>

Returns the query dataset specification in DELETE/INSERT operations.

pub fn using_datasets_mut(&mut self) -> impl Iterator<Item = &mut QueryDataset>

Returns the query dataset specification in DELETE/INSERT operations.

Trait Implementations

impl Clone for Update

fn clone(&self) -> Update

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Update

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

Formats the value using the given formatter.

impl Display for Update

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

Formats the value using the given formatter.

impl From<Update> for Update

fn from(update: Update) -> Self

Converts to this type from the input type.

impl FromStr for Update

type Err = SparqlSyntaxError

The associated error which can be returned from parsing.

fn from_str(update: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Update

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 Update

fn eq(&self, other: &Update) -> 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 TryFrom<&String> for Update

type Error = SparqlSyntaxError

The type returned in the event of a conversion error.

fn try_from(update: &String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for Update

type Error = SparqlSyntaxError

The type returned in the event of a conversion error.

fn try_from(update: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Update
