Struct SlackClientBuilder 

pub struct SlackClientBuilder { /* private fields */ }

Builder for SlackClient.

Implementations

impl SlackClientBuilder

pub fn token(self, token: impl Into<String>) -> Self

pub fn http_client(self, http: Client) -> Self

Uses an existing reqwest::Client so the application and Slack share one connection pool. Its own settings (timeouts, proxy, …) are used as they are.

Without it, the client is built with a 30 second request timeout and a 10 second connect timeout.

pub fn base_url(self, base_url: impl Into<String>) -> Self

Base URL of the API (default https://slack.com/api/). Set it for GovSlack (https://slack-gov.com/api/) or for a mock server in tests.

pub fn max_retries(self, max_retries: u32) -> Self

How many times a request is resent after a 429, waiting for Retry-After each time.

The default is 0: a 429 is returned at once as SlackError::RateLimited with the Retry-After value, because only the caller knows how long a request may wait. Other failures (5xx, network errors) are never retried, to avoid posting twice.

pub fn build(self) -> SlackClient

Builds the client.

Panics

When no http_client was given and the TLS backend cannot be initialized, like reqwest::Client::new().

Trait Implementations

impl Default for SlackClientBuilder

fn default() -> Self

Returns the “default value” for a type.
