Struct PresenceRunner 

pub struct PresenceRunner { /* private fields */ }

A runner that manages the Discord RPC background task. Create a runner, configure it, run it to get a client handle, then clone the handle for sharing.

Implementations

impl PresenceRunner

pub fn new(client_id: impl Into<String>) -> Self

Create a new PresenceRunner instance. Requires the client ID of your chosen app from the Discord Developer Portal.

pub fn on_retry<F: Fn(usize) + Send + Sync + 'static>(self, f: F) -> Self

Runs a particular closure when retrying for socket creation or handshake.

This can fire multiple times, or for a limited amount depending on the amount of maximum retries that has been set (through PresenceRunner::set_max_retries).

The closure parameter is the count of retries done at the time of its execution.

Sets the amount of maximum retries to do on socket creation and handshakes before the runner should give up.

By default this is set to 0 internally, which means the inner loop would retry indefinitely.

Run the runner. Must be called before any client handle operations.

pub fn clone_handle(&self) -> PresenceClient

Returns a clone of the client handle for sharing.

pub async fn wait(&mut self) -> Result<(), PresenceRunnerError>

Waits for the IPC task to finish.

NOTE: If there’s no join_handle present, the function will do nothing and just return blank.
