Implementations

impl Port

pub fn send(&self, msg: IpcMessage) -> Result<(), IpcError>

Send a message to this port.

If the queue is full, the calling task blocks until space is available. Returns Err(IpcError::PortDestroyed) if the port is destroyed while the sender is blocked.

pub fn recv(&self) -> Result<IpcMessage, IpcError>

Receive a message from this port.

If the queue is empty, the calling task blocks until a message arrives. Returns Err(IpcError::PortDestroyed) if the port is destroyed while the receiver is blocked.

pub fn try_recv(&self) -> Result<Option<IpcMessage>, IpcError>

Try to receive a message from this port without blocking.

Returns Ok(Some(msg)) if a message was available, Ok(None) if empty, or Err(IpcError::PortDestroyed) if the port is destroyed.

pub fn has_messages(&self) -> bool

Returns whether messages is available.

pub fn can_send(&self) -> bool

Returns whether this can send.

pub fn is_destroyed(&self) -> bool

Returns whether destroyed.
