Struct ChannelMessageEnvelope 

pub struct ChannelMessageEnvelope {
    pub id: String,
    pub tenant: TenantCtx,
    pub channel: String,
    pub session_id: String,
    pub reply_scope: Option<ReplyScope>,
    pub from: Option<Actor>,
    pub to: Vec<Destination>,
    pub correlation_id: Option<String>,
    pub text: Option<String>,
    pub attachments: Vec<Attachment>,
    pub metadata: MessageMetadata,
    pub extensions: BTreeMap<String, Value>,
}

Envelope for channel messages exchanged with adapters.

NOTE: Intentionally not #[non_exhaustive] — consumers construct this type directly via struct literals (see greentic-messaging-providers, etc). Adding a new field is a coordinated breaking change that requires a minor version bump and synchronized updates across consumer submodules.

Fields

id: String

Stable identifier for the message.

tenant: TenantCtx

Tenant context propagated with the message.

channel: String

Abstract channel identifier or type.

session_id: String

Conversation or thread identifier.

reply_scope: Option<ReplyScope>

Optional reply scope that can be used for resumption.

from: Option<Actor>

Optional actor (sender/initiator) associated with the message (primarily ingress).

to: Vec<Destination>

Outbound destinations for egress. Empty means “unspecified” and may be satisfied by provider config defaults.

correlation_id: Option<String>

Optional correlation identifier used by outbound adapters.

text: Option<String>

Optional text content.

attachments: Vec<Attachment>

Attachments included with the message.

metadata: MessageMetadata

Free-form metadata for adapters and flows.

extensions: BTreeMap<String, Value>

Structured provider-agnostic and provider-native extension data.

Use well-known keys from extensions::ext_keys to avoid typos. Values are typed JSON (serde_json::Value) — no re-serialization needed at provider boundaries.

Trait Implementations

impl Clone for ChannelMessageEnvelope

fn clone(&self) -> ChannelMessageEnvelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelMessageEnvelope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChannelMessageEnvelope

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChannelMessageEnvelope

fn eq(&self, other: &ChannelMessageEnvelope) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for ChannelMessageEnvelope

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
