Struct Client 

pub struct Client { /* private fields */ }

Main client for interacting with IG Markets API

This client provides a unified interface for all IG Markets API operations, including market data, account management, and order execution.

Implementations

impl Client

pub fn try_new() -> Result<Self, AppError>

Creates a new client instance without performing initial authentication, returning an error if the underlying HTTP client cannot be constructed.

This is the sole constructor for Client: it builds the underlying HttpClient via HttpClient::new_lazy and surfaces a client-construction failure as a typed AppError instead of panicking.

Returns

• Ok(Client) - A client ready to use with the default configuration.
• Err(AppError) - If the underlying HTTP client cannot be constructed.

Errors

Returns AppError::Network if the underlying reqwest client cannot be built (e.g. the system TLS backend fails to initialize).

pub async fn ws_info(&self) -> Result<WebsocketInfo, AppError>

Gets WebSocket connection information for Lightstreamer, reusing the cached session.

Delegates to HttpClient::ws_info, which returns the cached session when it is valid and only logs in when needed.

Returns

• Ok(WebsocketInfo) - Server endpoint, authentication tokens, and account ID for the current session.
• Err(AppError) - If session retrieval (login / refresh) fails.

Errors

Returns AppError when the session cannot be retrieved.

pub async fn get_ws_info(&self) -> WebsocketInfo

👎Deprecated:

use ws_info() which reuses the cached session and returns a typed error instead of a default-on-error WebsocketInfo

Gets WebSocket connection information for Lightstreamer

Returns

• WebsocketInfo containing server endpoint, authentication tokens, and account ID
