Struct Message 

pub struct Message {
    pub id: String,
    pub name: Option<String>,
    pub role: MessageRole,
    pub parts: Vec<Part>,
    pub created_at: i64,
    pub agent_id: Option<String>,
    pub parts_metadata: Option<PartsMetadata>,
}

Fields

id: String

name: Option<String>

role: MessageRole

parts: Vec<Part>

created_at: i64

agent_id: Option<String>

The ID of the agent that generated this message (for Assistant messages)

parts_metadata: Option<PartsMetadata>

Per-part metadata used to control part behavior during save. Parts with save: false will be filtered out before saving to the database. This field is used for processing only and is not persisted.

Implementations

impl Message

pub fn user(task: String, name: Option<String>) -> Self

pub fn system(task: String, name: Option<String>) -> Self

pub fn assistant(task: String, name: Option<String>) -> Self

pub fn developer(task: String, name: Option<String>) -> Self

pub fn tool_response( tool_call_id: String, tool_name: String, result: &Value, ) -> Self

pub fn as_text(&self) -> Option<String>

pub fn tool_calls(&self) -> Vec<ToolCall>

pub fn tool_responses(&self) -> Vec<ToolResponse>

pub fn has_tool_response(&self) -> bool

pub fn filter_for_save(&self, parts_metadata: Option<&PartsMetadata>) -> Self

Filter parts based on metadata, returning a new Message with only saveable parts. Parts with save: false in the parts_metadata will be filtered out. If parts_metadata is None, all parts are included.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl Default for Message

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Message

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Message> for MessageMetadata

fn from(message: Message) -> Self

Converts to this type from the input type.

impl JsonSchema for Message

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for Message

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Message> for Message

type Error = AgentError

The type returned in the event of a conversion error.

fn try_from(message: Message) -> Result<Self, Self::Error>
