Struct InitializeParams 

pub struct InitializeParams {
    pub channel: Uri,
    pub protocol_versions: Vec<String>,
    pub client_id: String,
    pub client_info: Option<Implementation>,
    pub initial_subscriptions: Option<Vec<Uri>>,
    pub locale: Option<String>,
    pub capabilities: Option<ClientCapabilities>,
}

Establishes a new connection and negotiates the protocol version. This MUST be the first message sent by the client.

Fields

channel: Uri

Channel URI this command targets.

protocol_versions: Vec<String>

Protocol versions the client is willing to speak, ordered from most preferred to least preferred. Each entry is a SemVer MAJOR.MINOR.PATCH string (e.g. "0.1.0").

The server selects one entry and returns it as InitializeResult.protocolVersion. If the server cannot speak any of the offered versions, it MUST return error code -32005 (UnsupportedProtocolVersion).

client_id: String

Unique client identifier

client_info: Option<Implementation>

Optional identity of the client implementation (name and version). Informational only — see {@link Implementation} for how it may and may not be used. Distinct from {@link InitializeParams.clientId | clientId}, which is an opaque per-connection identifier used for reconnection, not a human-readable implementation name.

initial_subscriptions: Option<Vec<Uri>>

URIs to subscribe to during handshake

locale: Option<String>

IETF BCP 47 language tag indicating the client’s preferred locale (e.g. "en-US", "ja"). The server SHOULD use this to localise user-facing strings such as confirmation option labels.

capabilities: Option<ClientCapabilities>

Optional client capability declarations.

Servers SHOULD only advertise features whose corresponding client capability is set here. Absent means “not declared” — the server MUST assume the client does not support the feature.

Trait Implementations

impl Clone for InitializeParams

fn clone(&self) -> InitializeParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitializeParams

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InitializeParams

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for InitializeParams

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
