Struct SessionMessage 

#[non_exhaustive]
pub struct SessionMessage {
    pub message_id: MessageId,
    pub sender_session_id: Option<SessionId>,
    pub recipient_session_id: Option<SessionId>,
    pub content: MaybeUndefined<Vec<ContentBlock>>,
    pub meta: MaybeUndefined<Meta>,
}

Available on crate feature unstable_protocol_v2 only.

UNSTABLE

This capability is not part of the spec yet, and may be removed or changed at any point.

An upsert for an inter-session message.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

message_id: MessageId

Identifier of this message within the enclosing session’s transcript.

sender_session_id: Option<SessionId>

Optional sending session identity; omission or null retains a known value.

recipient_session_id: Option<SessionId>

Optional receiving session identity; omission or null retains a known value.

content: MaybeUndefined<Vec<ContentBlock>>

Omitted leaves content unchanged; null clears it; a concrete array replaces the whole content collection.

meta: MaybeUndefined<Meta>

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Omitted leaves the stored metadata unchanged; null clears it. An object patches the stored metadata by top-level key: keys it omits are unchanged, a key set to null is removed, and any other value replaces that key’s stored value without merging nested objects. Beyond this patch rule, implementations MUST NOT make assumptions about values at these keys.

See protocol docs: Metadata Patches

Implementations

impl SessionMessage

pub fn new(message_id: impl Into<MessageId>) -> Self

Available on crate feature unstable_subagents only.

Builds a message upsert with its transcript-local ID.

pub fn sender_session_id( self, sender_session_id: impl IntoOption<SessionId>, ) -> Self

Available on crate feature unstable_subagents only.

Supplies the sending session identity, when known.

pub fn recipient_session_id( self, recipient_session_id: impl IntoOption<SessionId>, ) -> Self

Available on crate feature unstable_subagents only.

Supplies the receiving session identity, when known.

pub fn content( self, content: impl IntoMaybeUndefined<Vec<ContentBlock>>, ) -> Self

Available on crate feature unstable_subagents only.

Replaces, clears, or leaves unchanged the message content.

pub fn meta(self, meta: impl IntoMaybeUndefined<Meta>) -> Self

Available on crate feature unstable_subagents only.

Patches, clears, or leaves unchanged message metadata.

A concrete object patches stored metadata by top-level key; see apply_meta_update.
