Trait Transport 

pub trait Transport {
    type Error;

    // Required methods
    async fn send(
        &self,
        to: &PublicKey,
        payload: &[u8],
        options: &SendOptions,
    ) -> Result<SendProgressTicket, Self::Error>;
    async fn send_all(
        &self,
        payload: &[u8],
        options: &SendOptions,
    ) -> Result<SendProgressTicket, Self::Error>;
}

A context through which UMSH frames can be sent.

Both LocalNode and BoundChannel implement this trait, allowing generic code over the transport context.

Important: Transport is a context abstraction, not a security abstraction. LocalNode::send() produces a unicast frame (destination- encrypted, only the recipient can decrypt). BoundChannel::send() produces a blind unicast frame (channel-encrypted — any node with the channel key can decrypt). Generic code over Transport must not assume identical delivery or privacy properties.

Required Associated Types

type Error

Required Methods

async fn send( &self, to: &PublicKey, payload: &[u8], options: &SendOptions, ) -> Result<SendProgressTicket, Self::Error>

Send a payload to a specific destination.

• On LocalNode: unicast (destination-encrypted)
• On BoundChannel: blind unicast (channel-encrypted)

async fn send_all( &self, payload: &[u8], options: &SendOptions, ) -> Result<SendProgressTicket, Self::Error>

Send a payload to all reachable nodes in this transport’s scope.

• On LocalNode: broadcast (unauthenticated)
• On BoundChannel: multicast (channel-encrypted)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
