Enum Side 

pub enum Side {
    Buy,
    Sell,
}

Represents the side of an order in trading, either buying or selling.

In financial markets, the “side” of an order indicates whether the trader is purchasing (Buy) or selling (Sell) an asset. For perpetual futures on Bybit, this determines whether the trader is opening a long position (Buy) or a short position (Sell). When writing trading bots, the side is critical for position management, as it affects margin requirements and exposure to price movements. For example, a Buy order in a rising market aims to profit from price increases, while a Sell order in a falling market aims to profit from price declines. Incorrectly setting the side can lead to unintended positions, so bots must validate this field against their strategy.

Variants

Buy

Represents a buy order, initiating a long position or closing a short position.

Sell

Represents a sell order, initiating a short position or closing a long position.

Implementations

impl Side

pub fn as_str(&self) -> &str

Converts the Side enum to its string representation.

This method is used to serialize the Side enum into a string format compatible with Bybit’s API, which expects “Buy” or “Sell”. Bots should use this method when constructing API requests to ensure correct formatting.
