Struct eventually::message::Envelope

pub struct Envelope<T>
where
    T: Message,
{
    pub message: T,
    pub metadata: Metadata,
}

Represents a Message packaged for persistance and/or processing by other parts of the system.

It carries both the actual message (i.e. a payload) and some optional Metadata.

Fields

message: T

The message payload.

metadata: Metadata

Optional metadata to provide additional context to the message.

Implementations

impl<T> Envelope<T>

where T: Message,

pub fn with_metadata(self, key: String, value: String) -> Self

Adds a new entry in the Envelope’s Metadata.

Trait Implementations

impl<T> Clone for Envelope<T>

where T: Message + Clone,

fn clone(&self) -> Envelope<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for Envelope<T>

where T: Message + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Envelope<T>

where T: Message + Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<T> for Envelope<T>

where T: Message,

fn from(message: T) -> Self

Converts to this type from the input type.

impl<T> PartialEq for Envelope<T>

where T: Message + PartialEq,

fn eq(&self, other: &Envelope<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Serialize for Envelope<T>

where T: Message + Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
