Struct TripleRef 

pub struct TripleRef<'a> {
    pub subject: TermRef<'a>,
    pub predicate: TermRef<'a>,
    pub object: TermRef<'a>,
}

Zero-copy triple reference for efficient operations

Fields

subject: TermRef<'a>

predicate: TermRef<'a>

object: TermRef<'a>

Implementations

impl<'a> TripleRef<'a>

pub fn new( subject: TermRef<'a>, predicate: TermRef<'a>, object: TermRef<'a>, ) -> Self

Create a new triple reference

pub fn from_triple(triple: &'a Triple) -> Self

Create from an owned triple

Quoted triples (RDF-star)

TermRef is a zero-copy, Copy view (&'a str payloads only), so it has no owned-string variant available to hold a freshly serialized quoted-triple description; a quoted subject/object is therefore mapped to the same non-identifying "<<quoted-triple>>" placeholder documented on crate::model::RdfTerm::as_str. Do not use the TermRef produced for a quoted-triple component as an identity or lookup key – distinct quoted triples are indistinguishable through this path. Code that needs real quoted-triple identity (e.g. OptimizedGraph’s own subject/object interning) serializes the full << s p o >> content instead; see intern_subject/ intern_object.

pub fn to_owned(&self) -> Result<Triple, OxirsError>

Convert to an owned triple
