Struct UeMap 

pub struct UeMap<K, V>
where
    K: ContainerElement,
    V: ContainerElement,
{ /* private fields */ }

A view into a UE TMap<K, V> property on a UObject.

Implementations

impl<K, V> UeMap<K, V>

where K: ContainerElement, V: ContainerElement,

pub fn new(owner: UObjectHandle, prop: FPropertyHandle) -> UeMap<K, V>

pub fn len(&self) -> Result<usize, RustealError>

Returns the number of key-value pairs in the map.

pub fn is_empty(&self) -> Result<bool, RustealError>

pub fn find(&self, key: &K) -> Result<V, RustealError>

Look up a value by key. Returns Err(PropertyNotFound) if the key is not in the map.

pub fn add(&self, key: &K, val: &V) -> Result<(), RustealError>

Insert or replace a key-value pair.

pub fn remove(&self, key: &K) -> Result<(), RustealError>

Remove a key from the map.

pub fn clear(&self) -> Result<(), RustealError>

Remove all key-value pairs.

pub fn get_pair(&self, logical_index: usize) -> Result<(K, V), RustealError>

Get the key-value pair at logical index (for iteration).

pub fn iter(&self) -> UeMapIter<'_, K, V>

Returns an iterator over key-value pairs.

impl<K, V> UeMap<K, V>

where K: ContainerElement, V: ContainerElement,

pub fn bulk_iter(&self) -> Result<BulkMapIter<K, V>, RustealError>

Bulk-fetch all key-value pairs as a lazy iterator (single FFI call).

impl<K, V> UeMap<K, V>

where K: ContainerElement + Hash + Eq, V: ContainerElement,

pub fn to_hash_map(&self) -> Result<HashMap<K, V>, RustealError>

Bulk-copy all key-value pairs to a HashMap in a single FFI call.

Trait Implementations

impl<K, V> Clone for UeMap<K, V>

where K: Clone + ContainerElement, V: Clone + ContainerElement,

fn clone(&self) -> UeMap<K, V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K, V> Copy for UeMap<K, V>

where K: Copy + ContainerElement, V: Copy + ContainerElement,

impl<'a, K, V> IntoIterator for &'a UeMap<K, V>

where K: ContainerElement, V: ContainerElement,

type Item = Result<(K, V), RustealError>

The type of the elements being iterated over.

type IntoIter = UeMapIter<'a, K, V>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a UeMap<K, V> as IntoIterator>::IntoIter

Creates an iterator from a value.
