Struct MessageEnvelope 

Source 
pub struct MessageEnvelope<P> { /* private fields */ }
Expand description

Runtime message envelope that keeps payloads separate from routing metadata.

Implementations§

Source§

impl<P> MessageEnvelope<P>

Source

pub const fn new(metadata: MessageMetadata, payload: P) -> Self

Create a message envelope.

Source

pub const fn metadata(&self) -> &MessageMetadata

Metadata that travels with the payload.

Source

pub const fn payload(&self) -> &P

Borrow the payload.

Source

pub fn into_payload(self) -> P

Consume the envelope and return the payload.

Source

pub fn map_payload<Q>(self, f: impl FnOnce(P) -> Q) -> MessageEnvelope<Q>

Transform the payload while preserving metadata.
