Struct rdftk_memgraph::MemGraph

pub struct MemGraph { /* fields omitted */ }

A very simple in-memory implementation of the Graph and NamedGraph traits.

Implementations

impl MemGraph

pub fn named(&mut self, name: IRIRef) -> &mut Self

pub fn with(&mut self, statements: Vec<Rc<Statement>>) -> &mut Self

pub fn mappings(&mut self, mappings: Rc<dyn PrefixMappings>) -> &mut Self
