Struct Subscription 

pub struct Subscription<'a> {
    pub op: &'a str,
    pub args: Vec<&'a str>,
}

Parameters for WebSocket subscription requests.

Used to construct a WebSocket subscription request to subscribe to real-time data streams, such as order book updates or trade events. Bots use this to configure WebSocket feeds for market monitoring and trading signals in perpetual futures trading.

Fields

op: &'a str

The operation type (e.g., “subscribe”).

Specifies the WebSocket operation, typically "subscribe" for subscribing to data streams. Bots must set this correctly to initiate subscriptions.

args: Vec<&'a str>

A list of subscription arguments.

Specifies the data streams to subscribe to, such as "orderbook.50.BTCUSDT" or "trade.BTCUSDT". Bots should provide valid topics to receive relevant market data.

Implementations

impl<'a> Subscription<'a>

pub fn new(op: &'a str, args: Vec<&'a str>) -> Self

Constructs a new Subscription with specified parameters.

Allows customization of the WebSocket subscription. Bots should use this to specify the operation and subscription arguments for their data needs.

pub fn default() -> Subscription<'a>

Creates a default Subscription.

Returns a subscription with op set to "subscribe" and an empty argument list. Suitable for testing but should be customized with valid topics for production.

Trait Implementations

impl<'a> Clone for Subscription<'a>

fn clone(&self) -> Subscription<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Subscription<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Subscription<'a>

fn default() -> Subscription<'a>

Returns the “default value” for a type.
