Struct AssistantContent 

pub struct AssistantContent {
    pub text: Option<String>,
    pub tool_calls: Vec<ToolCall>,
}

Content carried by an AgentMessage::Assistant turn.

A flat struct with optional text and a (possibly empty) tool_calls vec. At the wire level, at least one of the two fields must be present — the hand-rolled Deserialize impl (in super::messages_serde) enforces this.

Serde

Serializes/deserializes as a flat map so it can be #[serde(flatten)]-ed directly into the parent AgentMessage object:

State	JSON fields
text only	"content": "..."
tool calls only	"tool_calls": [...]
both	"content": "...", "tool_calls": [...]

Custom Serialize and Deserialize impls are in super::messages_serde.

Fields

text: Option<String>

Optional text content from the model. None when the model produced only tool calls with no text preamble.

tool_calls: Vec<ToolCall>

Tool calls requested by the model. Empty when the model produced a text-only response (final answer).

Implementations

impl AssistantContent

pub fn with_replaced_tool_calls(self, calls: Vec<ToolCall>) -> Self

Consume self and return a new value with calls as the tool-call list, preserving any existing text content.
