Trait MetaDataType 

pub trait MetaDataType<'a, M, C>
where
    Self: Sized,
    M: MetaDataType<'a, M, C>,
    C: ContentType<'a, M, C>,
{
    type SendContext: ContextType;
    type ReceiveContext: ContextType;

    // Required methods
    fn send(
        self,
        stream: &mut TcpStream,
        context: Option<Self::SendContext>,
    ) -> Result<Option<<C as ContentType<'a, M, C>>::SendContext>, Error>;
    fn receive(
        stream: &mut TcpStream,
        context: &Option<Self::ReceiveContext>,
    ) -> Result<(Self, Option<<C as ContentType<'a, M, C>>::ReceiveContext>), Error>;
}

Trait that needs to be implemented for type that will be used as metadata inside a message.

Required Associated Types

type SendContext: ContextType

Context provided to MetaDataType::send from TcpMessage::send.

type ReceiveContext: ContextType

Context provided to MetaDataType::receive.

Required Methods

fn send( self, stream: &mut TcpStream, context: Option<Self::SendContext>, ) -> Result<Option<<C as ContentType<'a, M, C>>::SendContext>, Error>

Send method used to send metadata inside TcpMessage::send.

Defines how are metadata send.

Returns an Option of ContentType::SendContext on associated C that is passed into ContentType::send in TcpMessage::send. or an Error if not.

Arguments

• stream – TcpStream on which are data being sent.
• context – Optional context provided from TcpMessage::send which is MetaDataType::SendContext

fn receive( stream: &mut TcpStream, context: &Option<Self::ReceiveContext>, ) -> Result<(Self, Option<<C as ContentType<'a, M, C>>::ReceiveContext>), Error>

Receive method used to receive metadata inside TcpMessage::receive.

Defines how metadata are received.

Returns a tuple of Self and an Option of ContentType::ReceiveContext on associated C that is passed into ContentType::receive in TcpMessage::send if successful or an Error if not.

Arguments

• stream – TcpStream on which are data being received.
• context – Optional context provided from TcpMessage::receive which is MetaDataType::ReceiveContext

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
