Struct AgentCapabilities 

#[non_exhaustive]
pub struct AgentCapabilities {
    pub load_session: bool,
    pub prompt_capabilities: PromptCapabilities,
    pub mcp_capabilities: McpCapabilities,
    pub session_capabilities: SessionCapabilities,
    pub auth: AgentAuthCapabilities,
    pub meta: Option<Map<String, Value>>,
}

Capabilities supported by the agent.

Advertised during initialization to inform the client about available features and content types.

See protocol docs: Agent Capabilities

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.

load_session: bool

Whether the agent supports session/load.

prompt_capabilities: PromptCapabilities

Prompt capabilities supported by the agent.

mcp_capabilities: McpCapabilities

MCP capabilities supported by the agent.

session_capabilities: SessionCapabilities

Session lifecycle and prompt capabilities advertised by the agent.

auth: AgentAuthCapabilities

Authentication-related capabilities supported by the agent.

meta: Option<Map<String, Value>>

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys.

See protocol docs: Extensibility

Implementations

impl AgentCapabilities

pub fn new() -> AgentCapabilities

Builds an empty AgentCapabilities; use builder methods to advertise supported sub-capabilities.

pub fn load_session(self, load_session: bool) -> AgentCapabilities

Whether the agent supports session/load.

pub fn prompt_capabilities( self, prompt_capabilities: PromptCapabilities, ) -> AgentCapabilities

Prompt capabilities supported by the agent.

pub fn mcp_capabilities( self, mcp_capabilities: McpCapabilities, ) -> AgentCapabilities

MCP capabilities supported by the agent.

pub fn session_capabilities( self, session_capabilities: SessionCapabilities, ) -> AgentCapabilities

Session capabilities supported by the agent.

pub fn auth(self, auth: AgentAuthCapabilities) -> AgentCapabilities

Authentication-related capabilities supported by the agent.

pub fn meta( self, meta: impl IntoOption<Map<String, Value>>, ) -> AgentCapabilities

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys.

See protocol docs: Extensibility

Trait Implementations

impl Clone for AgentCapabilities

fn clone(&self) -> AgentCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AgentCapabilities

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

Formats the value using the given formatter.

impl Default for AgentCapabilities

fn default() -> AgentCapabilities

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AgentCapabilities

fn deserialize<__D>( __deserializer: __D, ) -> Result<AgentCapabilities, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for AgentCapabilities

impl IntoV2 for AgentCapabilities

type Output = AgentCapabilities

The corresponding v2 draft type.

fn into_v2( self, ) -> Result<<AgentCapabilities as IntoV2>::Output, ProtocolConversionError>

Converts this value into the corresponding v2 draft type.

impl JsonSchema for AgentCapabilities

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 PartialEq for AgentCapabilities

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
