Struct AttributableMap 

pub struct AttributableMap<T: Attributable> { /* private fields */ }

A map of Attributable items keyed by their signer index.

The key for each item is automatically inferred from Attributable::signer(). Each signer can insert at most one item.

Implementations

impl<T: Attributable> AttributableMap<T>

pub fn new(participants: usize) -> Self

Creates a new AttributableMap with the given number of participants.

pub fn clear(&mut self)

Clears all existing items from the AttributableMap.

pub fn insert(&mut self, item: T) -> bool

Inserts an item into the map, using Attributable::signer() as the key, if it has not been added yet.

Returns true if the item was inserted, false if an item from this signer already exists or if the signer index is out of bounds.

pub const fn len(&self) -> usize

Returns the number of items in the AttributableMap.

pub const fn is_empty(&self) -> bool

Returns true if the AttributableMap is empty.

pub fn get(&self, signer: u32) -> Option<&T>

Returns a reference to the item associated with the given signer, if present.

pub fn iter(&self) -> impl Iterator<Item = &T>

Returns an iterator over items in the map, ordered by signer index (Attributable::signer()).
