Struct Update

pub struct Update {
    pub base_iri: Option<Iri<String>>,
    pub operations: Vec<GraphUpdateOperation>,
}

A parsed SPARQL update.

use spargebra::Update;

let update_str = "CLEAR ALL ;";
let update = Update::parse(update_str, None)?;
assert_eq!(update.to_string().trim(), update_str);
assert_eq!(update.to_sse(), "(update (clear all))");

Fields

base_iri: Option<Iri<String>>

The update base IRI.

operations: Vec<GraphUpdateOperation>

The update operations.

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 to_sse(&self) -> String

Formats using the SPARQL S-Expression syntax.

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 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
