Struct Envelope 

pub struct Envelope<M = AnyMessage> { /* private fields */ }

Implementations

impl<M> Envelope<M>

where M: Message,

pub fn into_erased(self) -> Envelope<AnyMessage>

impl<M> Envelope<M>

pub fn new(header: EnvelopeHeader, message: M) -> Self

pub fn header(&self) -> &EnvelopeHeader

impl Envelope<AnyMessage>

pub fn cast<M>(self) -> Result<Envelope<M>, Self>

where M: Message,

pub fn peek<M>(&self) -> Option<&M>

where M: Message,

pub fn is<M>(&self) -> bool

where M: Message,

pub fn tid(&self) -> TypeId

pub fn message_name(&self) -> &str

pub fn log_unhandled(&self)

Log an unmatched message and drop it.

The dispatch! macro calls this for a message that no arm matched when the match has no catch-all arm. The message is logged at WARN (with its header and type name) and dropped — mirroring the fire-and-forget semantics elsewhere in the runtime, so an unexpected message from any peer no longer panics and kills the actor.

A dispatch! used in value position must supply its own catch-all arm, because this fallback evaluates to ().

impl<M> Envelope<M>

pub fn take(self) -> (M, Envelope<()>)

Trait Implementations

impl<M> Debug for Envelope<M>

Formats the value using the given formatter.

impl From<Envelope<()>> for EnvelopeHeader

fn from(value: Envelope<()>) -> Self
