Enum RpcMessage 

pub enum RpcMessage {
    Request {
        msgid: u32,
        method: String,
        params: Value,
    },
    Response {
        msgid: u32,
        error: Value,
        result: Value,
    },
    Notify {
        method: String,
        params: Value,
    },
}

A single RPC message on the wire.

Variants

Request

Caller asks for a method invocation; expects a Response with matching msgid.

Fields

msgid: u32

method: String

params: Value

Response

Reply to a Request with the same msgid. Exactly one of error/result is meaningful; the other should be nil (Value::Nil).

Fields

msgid: u32

error: Value

result: Value

Notify

One-way message; no Response is expected.

Fields

method: String

params: Value

Implementations

impl RpcMessage

pub fn request(msgid: u32, method: impl Into<String>, params: Value) -> Self

Construct a Request.

pub fn response_ok(msgid: u32, result: Value) -> Self

Construct a Response carrying a successful result. error is set to Nil.

pub fn response_err(msgid: u32, error: Value) -> Self

Construct a Response carrying an error. result is set to Nil.

pub fn notify(method: impl Into<String>, params: Value) -> Self

Construct a Notify.

Trait Implementations

impl Clone for RpcMessage

fn clone(&self) -> RpcMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RpcMessage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RpcMessage

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Encoder<RpcMessage> for FrameCodec

type Error = Error

The type of encoding errors.

fn encode(&mut self, item: RpcMessage, dst: &mut BytesMut) -> Result<()>

Encodes a frame into the buffer provided.

impl PartialEq for RpcMessage

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

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
