What a Source can contribute to a crate::types::Brief.

One Contribution becomes (eventually) one crate::types::BriefMessage or one ToolSchema in the final brief, modulo budget pruning and governance redaction. The variants intentionally mirror crate::types::BriefMessage plus a ContributionContent::System variant for system-prompt text and a ContributionContent::Tool variant for tool catalog entries.

Variants

System

System-prompt text. Multiple contributions are concatenated in source order by the builder.

Fields

text: String

System-prompt text.

Text

Plain text content under a role.

Fields

role: Role

Role this message is attributed to.

content: String

Message body.

Image

Image content under a role.

Fields

role: Role

Role this image is attributed to.

data: ImageData

The image payload.

alt: Option<String>

Optional alt / caption text.

ToolCall

A prior tool invocation, replayed into the conversation.

Fields

id: String

Provider-issued tool-call ID.

name: String

Tool name (matches a ToolSchema::name).

args: Value

JSON arguments the model passed.

ToolResult

The result returned for a prior tool call.

Fields

id: String

Tool-call ID this result responds to.

content: String

Serialised result content.

Tool

A tool schema to be made available to the model this turn.

Fields

schema: ToolSchema

The tool schema. Its source field is set by the builder when the contribution is admitted.

Trait Implementations

impl Clone for ContributionContent

fn clone(&self) -> ContributionContent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContributionContent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContributionContent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ContributionContent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
