Fields

capabilities: ServerCapabilities

instructions: Option<String>

Instructions describing how to use the server and its features.

This can be used by clients to improve the LLM’s understanding of available tools, resources, etc. It can be thought of like a “hint” to the model. For example, this information MAY be added to the system prompt.

meta: Map<String, Value>

This result property is reserved by the protocol to allow clients and servers to attach additional metadata to their responses.

protocol_version: String

The version of the Model Context Protocol that the server wants to use. This may not match the version that the client requested. If the client cannot support this version, it MUST disconnect.

server_info: Implementation

Trait Implementations

impl Clone for InitializeResult

fn clone(&self) -> InitializeResult

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InitializeResult

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InitializeResult

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&InitializeResult> for InitializeResult

fn from(value: &InitializeResult) -> Self

Converts to this type from the input type.

impl From<&InitializeResult> for ServerResult

fn from(value: &InitializeResult) -> Self

Converts to this type from the input type.

impl From<InitializeResult> for ServerResult

fn from(value: InitializeResult) -> Self

Converts to this type from the input type.

impl PartialEq for InitializeResult

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
