Struct Messages 

pub struct Messages<M: Message> { /* private fields */ }

Container for managing messages of a specific type.

This struct maintains separate lists for messages from the current and previous frames.

Implementations

impl<M: Message> Messages<M>

pub const fn new() -> Self

Creates a new Messages container.

pub fn send(&mut self, message: M) -> MessageId<M>

Sends a new message, assigning it a unique MessageId.

The message is added to the current_messages list.

Arguments

• message - The message to be sent.

Returns

A MessageId uniquely identifying the sent message.

pub fn swap(&mut self)

Swaps the current and previous frame message lists.

This should be called at the start of each new frame (update) to transition messages appropriately.

pub fn iter_current(&self) -> MessagesIterator<'_, M>

Returns an iterator over the current frame’s messages.

pub fn iter_previous(&self) -> MessagesIterator<'_, M>

Returns an iterator over the previous frame’s messages.

pub fn len_current(&self) -> usize

Returns the number of messages in the current frame.

pub fn len_previous(&self) -> usize

Returns the number of messages in the previous frame.

pub fn is_empty_current(&self) -> bool

Checks if there are no messages in the current frame.

pub fn is_empty_previous(&self) -> bool

Checks if there are no messages in the previous frame.

Trait Implementations

impl<M: Debug + Message> Debug for Messages<M>

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

Formats the value using the given formatter.

impl<M: Default + Message> Default for Messages<M>

fn default() -> Messages<M>

Returns the “default value” for a type.

impl<M: Message> MessageContainer for Messages<M>

fn swap(&mut self)

Swaps the current and previous frame message lists.

fn as_any(&self) -> &dyn Any

Provides a reference to the container as Any for downcasting.

fn as_any_mut(&mut self) -> &mut dyn Any

Provides a mutable reference to the container as Any for downcasting.
