Struct GraphValidation

pub struct GraphValidation { /* private fields */ }

The In-Memory Graph Validation algorithm.

Implementations

impl GraphValidation

pub fn from_path( data: &Path, data_format: RDFFormat, base: Option<&str>, mode: ShaclValidationMode, ) -> Result<Self, ValidateError>

Returns an In-Memory Graph validation SHACL processor.

Arguments

• data - A path to the graph’s serialization file
• data_format - Any of the possible RDF serialization formats
• base - An optional String, the base URI
• mode - Any of the possible SHACL validation modes

Examples

use std::path::Path;

use shacl_validation::shacl_processor::GraphValidation;
use shacl_validation::shacl_processor::ShaclValidationMode;
use shacl_validation::shacl_processor::ShaclProcessor;
use srdf::RDFFormat;

let graph_validation = GraphValidation::new(
    Path::new("../examples/book_conformant.ttl"), // example graph (refer to the examples folder)
    RDFFormat::Turtle, // serialization format of the graph
    None, // no base is defined
    ShaclValidationMode::Native, // use the Native mode (performance)
);

pub fn from_graph(graph: Graph, mode: ShaclValidationMode) -> GraphValidation

Trait Implementations

impl ShaclProcessor<RdfData> for GraphValidation

fn store(&self) -> &RdfData

fn runner(&self) -> &dyn Engine<RdfData>

fn validate( &self, shapes_graph: &CompiledSchema<S>, ) -> Result<ValidationReport, ValidateError>

Executes the Validation of the provided Graph, in any of the supported formats, against the shapes graph passed as an argument. As a result, the Validation Report generated from the validation process is returned.
