Struct AnyMap 

pub struct AnyMap { /* private fields */ }

A type-erased map storing values of different types by their TypeId.

AnyMap allows storing and retrieving values of any type that implements Clone + Send + Sync. The map uses TypeId as keys, enabling type-safe lookups while maintaining type erasure through boxed trait objects.

Examples

use any_container::AnyMap;

let mut map = AnyMap::new();
map.insert(42i32);
map.insert("world".to_string());

assert_eq!(map.len(), 2);
assert_eq!(*map.get::<i32>().unwrap(), 42);

Implementations

impl AnyMap

pub fn new() -> AnyMap

Creates a new empty AnyMap.

pub fn with_capacity(capacity: usize) -> AnyMap

Creates a new empty AnyMap with the specified capacity.

pub fn capacity(&self) -> usize

Returns the number of elements that the map can hold without reallocating.

pub fn reserve(&mut self, additional: usize)

Reserves capacity for at least additional more elements in the map. The map may reserve more space than requested to avoid frequent reallocations.

pub fn shrink_to_fit(&mut self)

Shrinks the capacity of the map as much as possible. This reduces the allocated memory to fit the current contents.

pub fn len(&self) -> usize

Returns the number of elements in the map.

pub fn is_empty(&self) -> bool

Returns true if the map contains no elements.

pub fn clear(&mut self)

Removes all elements from the map.

pub fn get<T: Any>(&self) -> Option<&T>

Returns a reference to the value corresponding to the type T.

pub fn get_mut<T: Any>(&mut self) -> Option<&mut T>

Returns a mutable reference to the value corresponding to the type T.

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

pub fn insert_boxed(&mut self, value: AnyCloneBox) -> Option<AnyCloneBox>

Inserts a boxed value into the map. If a value of the same TypeId already exists, it will be replaced and the old value will be returned. This method is useful when you already have an AnyCloneBox instance.

pub fn try_insert<T: Any + Clone + Send + Sync>( &mut self, value: T, ) -> Result<(), T>

Inserts a value of type T into the map. If a value of type T already exists, it will not be replaced and the new value will be returned as an error.

pub fn try_insert_boxed( &mut self, value: AnyCloneBox, ) -> Result<(), AnyCloneBox>

Inserts a boxed value into the map. If a value of the same type already exists, it will not be replaced and the new value will be returned as an error.

pub fn remove<T: Any>(&mut self) -> Option<T>

Removes the stored value of type T from the map and returns it, if it exists.

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

Returns true if the map contains a value of type T.

Trait Implementations

impl Clone for AnyMap

fn clone(&self) -> AnyMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnyMap

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

Formats the value using the given formatter.

impl Default for AnyMap

fn default() -> Self

Returns the “default value” for a type.
