Struct PropertyMapping

pub struct PropertyMapping { /* private fields */ }

A property mapping maps human-readable property and attribute labels to ObjIds.

Implementations

impl PropertyMapping

pub fn add( &mut self, property_label: String, attribute_label: String, attribute_id: Id128<Object>, )

Add an property/attribute/attribute-id triple to the mapping.

pub fn attribute_object_id( &self, property_label: &str, attribute_label: &str, ) -> Option<Id128<Object>>

Get the object ID of a single property/attribute label pair, if found.

pub fn translate<'a>( &self, attributes: impl IntoIterator<Item = (&'a str, &'a str)>, ) -> HashSet<Id128<Any>, BuildHasherDefault<FnvHasher>>

Translate the given property/attribute labels to underlying ObjIds.

Trait Implementations

impl Clone for PropertyMapping

fn clone(&self) -> PropertyMapping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for PropertyMapping

fn default() -> PropertyMapping

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a PropertyMapping

type IntoIter = Iter<'a, String, AttributeMappings>

Which kind of iterator are we turning this into?

type Item = (&'a String, &'a AttributeMappings)

The type of the elements being iterated over.

fn into_iter(self) -> <&'a PropertyMapping as IntoIterator>::IntoIter

Creates an iterator from a value.

impl IntoIterator for PropertyMapping

type IntoIter = IntoIter<String, AttributeMappings>

Which kind of iterator are we turning this into?

type Item = (String, AttributeMappings)

The type of the elements being iterated over.

fn into_iter(self) -> <PropertyMapping as IntoIterator>::IntoIter

Creates an iterator from a value.
