Implementations

impl ClientBuilder

pub fn new(username: impl Into<String>, api_key: impl Into<String>) -> Self

Start a builder with credentials. Call Self::build to finalize.

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

Override the API base URL (useful for mock servers).

pub fn timeout(self, v: Duration) -> Self

Total request timeout (default 30s).

pub fn connect_timeout(self, v: Duration) -> Self

TCP connect timeout (default 10s).

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

Override the User-Agent header (default clicksend-rs/<version>).

pub fn retry(self, v: RetryConfig) -> Self

Configure retry behavior. Default is no retry.

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

Plug your own reqwest::Client — timeout/connect/UA on the builder are then ignored.

pub fn build(self) -> Result<Client, ClickSendError>

Finalize. Errors with ClickSendError::InvalidConfig on empty creds.
