Struct WsHandlers 

pub struct WsHandlers {
    pub on_open: Option<fn(OnOpenCallbackArgs)>,
    pub on_message: Option<fn(OnMessageCallbackArgs)>,
    pub on_close: Option<fn(OnCloseCallbackArgs)>,
}

Handlers initialized by the canister and triggered by the CDK.

Note: if the callbacks that you define here trap for some reason, the CDK will disconnect the client with principal args.client_principal. However, the client won’t be notified until at least the next time it will try to send a message to the canister.

Fields

on_open: Option<fn(OnOpenCallbackArgs)>

on_message: Option<fn(OnMessageCallbackArgs)>

on_close: Option<fn(OnCloseCallbackArgs)>

Trait Implementations

impl Clone for WsHandlers

fn clone(&self) -> WsHandlers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WsHandlers

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

Formats the value using the given formatter.

impl Default for WsHandlers

fn default() -> WsHandlers

Returns the “default value” for a type.

impl PartialEq for WsHandlers

fn eq(&self, other: &WsHandlers) -> 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.
