Struct InitializeRequestParams 

pub struct InitializeRequestParams {
    pub meta: Option<Meta>,
    pub protocol_version: ProtocolVersion,
    pub capabilities: ClientCapabilities,
    pub client_info: Implementation,
}

Parameters sent by a client when initializing a connection to an MCP server.

This contains the client’s protocol version, capabilities, and implementation information, allowing the server to understand what the client supports.

Fields

meta: Option<Meta>

Protocol-level metadata for this request (SEP-1319)

protocol_version: ProtocolVersion

The MCP protocol version this client supports

capabilities: ClientCapabilities

The capabilities this client supports (sampling, roots, etc.)

client_info: Implementation

Information about the client implementation

Trait Implementations

impl Clone for InitializeRequestParams

fn clone(&self) -> InitializeRequestParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitializeRequestParams

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InitializeRequestParams

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for InitializeRequestParams

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 InitializeRequestParams

fn eq(&self, other: &InitializeRequestParams) -> 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 RequestParamsMeta for InitializeRequestParams

fn meta(&self) -> Option<&Meta>

Get a reference to the meta field

fn meta_mut(&mut self) -> &mut Option<Meta>

Get a mutable reference to the meta field

fn set_meta(&mut self, meta: Meta)

Set the meta field

fn progress_token(&self) -> Option<ProgressToken>

Get the progress token from meta, if present

fn set_progress_token(&mut self, token: ProgressToken)

Set a progress token in meta

impl Serialize for InitializeRequestParams

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
