Enum BriefMessage 

pub enum BriefMessage {
    Text {
        role: Role,
        content: String,
        source: SourceId,
    },
    Image {
        role: Role,
        data: ImageData,
        alt: Option<String>,
        source: SourceId,
    },
    ToolCall {
        id: String,
        name: String,
        args: Value,
        source: SourceId,
    },
    ToolResult {
        id: String,
        content: String,
        source: SourceId,
    },
}

One message in a Brief’s conversation transcript.

Tagged with the SourceId of the contributing source so the BriefReceipt can attribute every visible byte. Variants mirror the Text | Image | ToolCall | ToolResult matrix.

Variants

Text

Plain text content under a role.

Fields

role: Role

Role this message is attributed to.

content: String

Message body.

source: SourceId

Source that contributed the message.

Image

Image content under a role (typically User for vision turns).

Fields

role: Role

Role this image is attributed to.

data: ImageData

The image payload.

alt: Option<String>

Optional alt / caption text for accessibility and fall-back.

source: SourceId

Source that contributed the image.

ToolCall

A tool invocation the model previously emitted. Carries the original tool call ID so a BriefMessage::ToolResult can be matched to it.

Fields

id: String

Provider-issued tool-call ID.

name: String

Tool name (matches a ToolSchema::name).

args: Value

JSON arguments the model passed.

source: SourceId

Source that contributed the call (typically a history source).

ToolResult

The result returned for a prior tool call.

Fields

id: String

Tool-call ID this result responds to.

content: String

Serialised result content.

source: SourceId

Source that contributed the result.

Implementations

impl BriefMessage

pub fn source(&self) -> &SourceId

The SourceId that produced this message.

Trait Implementations

impl Clone for BriefMessage

fn clone(&self) -> BriefMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BriefMessage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BriefMessage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BriefMessage

fn eq(&self, other: &BriefMessage) -> 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 BriefMessage

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
