Struct AnyMultiMap 

pub struct AnyMultiMap { /* private fields */ }

A type-erased multimap storing multiple values per type.

AnyMultiMap allows storing multiple values of the same type, with each type identified by its TypeId. Values are stored in vectors behind trait objects, enabling type-erased access while maintaining type safety.

Examples

use any_container::AnyMultiMap;

let mut multimap = AnyMultiMap::new();
multimap.insert(1i32);
multimap.insert(2i32);
multimap.insert("hello".to_string());

assert_eq!(multimap.len::<i32>(), 2);
assert_eq!(multimap.get::<i32>(), &[1, 2]);

assert_eq!(multimap.len::<String>(), 1);
assert_eq!(multimap.get::<String>(), &["hello".to_string()]);

Implementations

impl AnyMultiMap

pub fn new() -> AnyMultiMap

Creates a new empty AnyMultiMap.

pub fn type_count(&self) -> usize

Returns the number of different types stored in the AnyMultiMap.

This counts unique types, not the total number of values.

pub fn len<T: Any + Send + Sync>(&self) -> usize

Returns the number of values of type T stored in the AnyMultiMap.

pub fn len_total(&self) -> usize

Returns the total number of values stored in the AnyMultiMap, across all types.

pub fn contains<T: Any + Send + Sync>(&self) -> bool

Returns true if there are values of type T stored in the AnyMultiMap.

pub fn contains_any(&self) -> bool

Returns true if there are any values stored in the AnyMultiMap, across all types.

pub fn is_empty<T: Any + Send + Sync>(&self) -> bool

Returns true if there are no values of type T stored in the AnyMultiMap.

pub fn is_completely_empty(&self) -> bool

Returns true if there are no values stored in the AnyMultiMap, across all types.

pub fn clear<T: Any + Send + Sync>(&mut self)

Removes all values of type T from the AnyMultiMap.

pub fn clear_all(&mut self)

Removes all values from the AnyMultiMap, across all types.

pub fn get<T: Any + Send + Sync>(&self) -> &[T]

Returns a slice of all values of type T stored in the AnyMultiMap. If no values of type T exist, an empty slice is returned.

pub fn get_mut<T: Any + Send + Sync>(&mut self) -> AnyVecMutRef<'_, T>

Returns a mutable reference to the vector values of type T stored in the AnyMultiMap. If no values of type T exist, a new vector is created and returned. This method is useful for adding multiple values of the same type efficiently.

pub fn insert<T: Any + Send + Sync>(&mut self, value: T)

Inserts a value of type T into the AnyMultiMap.

Note

This is a convenience method that calls get_mut and pushes the value into the vector. If you need to insert multiple values of the same type, consider using get_mut directly to avoid repeated lookups.

pub fn insert_boxed(&mut self, value: AnyCloneBox)

Inserts a boxed value of any type into the AnyMultiMap.

Trait Implementations

impl Debug for AnyMultiMap

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

Formats the value using the given formatter.

impl Default for AnyMultiMap

fn default() -> Self

Returns the “default value” for a type.
