Struct FerroPropertyDictionary 

pub struct FerroPropertyDictionary<TValue> { /* private fields */ }

Stores values with FerroProperty as key.

This struct is very similar to a sorted list, with the following differences:

• The key is the id of the property, allowing very fast lookups.
• The entries are stored in one array, which is the only heap allocation.
• It is a plain value: the owner mutates it in place.

Implementations

impl<TValue> FerroPropertyDictionary<TValue>

pub fn new() -> Self

Initializes a new instance.

pub fn new_with_capacity(capacity: usize) -> Self

Initializes a new instance with the specified initial capacity.

pub fn count(&self) -> usize

Gets the number of items in the collection.

pub fn get(&self, property: &FerroProperty) -> &TValue

Gets the value associated with the specified property (the getter of the indexer by property).

Panics when the property is not found.

pub fn set(&mut self, property: &FerroProperty, value: TValue)

Sets the value associated with the specified property (the setter of the indexer by property). An existing value is replaced.

pub fn get_at(&self, index: usize) -> &TValue

Gets the value at the specified index (the indexer by index).

Panics when the index is not less than count.

pub fn add(&mut self, property: &FerroProperty, value: TValue)

Adds the specified property and value to the dictionary.

Panics when the dictionary has the property already.

pub fn clear(&mut self)

Removes all property and values from the dictionary.

pub fn contains_key(&self, property: &FerroProperty) -> bool

Determines whether the dictionary contains the specified property.

pub fn get_value(&self, index: usize) -> &TValue

Gets the value at the specified index.

Panics when the index is not less than count.

pub fn remove(&mut self, property: &FerroProperty) -> bool

Removes the value with the specified property from the dictionary.

Returns true if the property was found and removed; otherwise false.

pub fn remove_value(&mut self, property: &FerroProperty) -> Option<TValue>

Removes the value with the specified property from the dictionary and returns it, or None when the property was not found.

pub fn remove_at(&mut self, index: usize)

Removes the element at the specified index from the dictionary.

Panics when the index is not less than count.

pub fn try_add(&mut self, property: &FerroProperty, value: TValue) -> bool

Attempts to add the specified property and value to the dictionary.

Returns false when the dictionary has the property already.

pub fn try_get_value(&self, property: &FerroProperty) -> Option<&TValue>

Gets the value associated with the specified property, or None when the dictionary does not contain it.
