Enum Response 

pub enum Response<V> {
    State {
        version: u64,
        view: V,
    },
    Ack,
    Error(String),
}

A message back to the client. V is a game’s View type.

Variants

State

A seat’s current view, plus the state version it was taken at.

version is a counter the host bumps once per applied action. Nothing consumes it yet; it is banked now so a later QuerySince(version) can answer “nothing changed” or send a delta without a wire-format break, and so a polling client can tell a stale snapshot from a fresh one.

Fields

version: u64

The state version this view was taken at.

view: V

The requesting seat’s view.

Ack

An action was accepted and applied. Deliberately carries no state: a write is acknowledged cheaply, and a client fetches the result with an explicit Request::Query only when it actually needs to render.

Error(String)

The request was rejected. The message is for humans and logs, not for programmatic matching.

Trait Implementations

impl<V: Clone> Clone for Response<V>

fn clone(&self) -> Response<V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V: Debug> Debug for Response<V>

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

Formats the value using the given formatter.

impl<'de, V> Deserialize<'de> for Response<V>

where V: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<V: PartialEq> PartialEq for Response<V>

fn eq(&self, other: &Response<V>) -> 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<V> Serialize for Response<V>

where V: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
