Enum DeltaChange 

pub enum DeltaChange {
    Insert {
        subject: String,
        predicate: String,
        object: String,
    },
    Delete {
        subject: String,
        predicate: String,
        object: String,
    },
}

A single modification to the underlying triple store.

Both variants carry the (subject, predicate, object) triple as owned Strings to keep the API self-contained.

Variants

Insert

A triple was added to the store.

Fields

subject: String

predicate: String

object: String

Delete

A triple was removed from the store.

Fields

subject: String

predicate: String

object: String

Implementations

impl DeltaChange

pub fn predicate(&self) -> &str

Return the predicate IRI of this change.

pub fn subject(&self) -> &str

Return the subject IRI of this change.

pub fn object(&self) -> &str

Return the object value of this change.

pub fn is_insert(&self) -> bool

Return true if this is an insertion.

Trait Implementations

impl Clone for DeltaChange

fn clone(&self) -> DeltaChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeltaChange

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

Formats the value using the given formatter.

impl PartialEq for DeltaChange

fn eq(&self, other: &DeltaChange) -> 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.
