Struct InitializeResult 

#[non_exhaustive]
pub struct InitializeResult {
    pub protocol_version: ProtocolVersion,
    pub capabilities: ServerCapabilities,
    pub server_info: Implementation,
    pub instructions: Option<String>,
}

The server’s response to an initialization request.

Contains the server’s protocol version, capabilities, and implementation information, along with optional instructions for the client.

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.

protocol_version: ProtocolVersion

The MCP protocol version this server supports

capabilities: ServerCapabilities

The capabilities this server provides (tools, resources, prompts, etc.)

server_info: Implementation

Information about the server implementation

instructions: Option<String>

Optional human-readable instructions about using this server

Implementations

impl InitializeResult

pub fn new(capabilities: ServerCapabilities) -> Self

Create a new InitializeResult with default protocol version and the given capabilities.

pub fn with_instructions(self, instructions: impl Into<String>) -> Self

Set instructions on this result.

pub fn with_server_info(self, server_info: Implementation) -> Self

Set the server info on this result.

pub fn with_protocol_version(self, protocol_version: ProtocolVersion) -> Self

Set the protocol version on this result.

Trait Implementations

impl Clone for InitializeResult

fn clone(&self) -> InitializeResult

Returns a duplicate 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 ServerResult

fn from(value: InitializeResult) -> Self

Converts to this type from the input type.

impl JsonSchema for InitializeResult

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 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.
