Enum TradingRequest 

pub enum TradingRequest {
    PostOrder,
    PostOrders {
        count: u32,
    },
    CancelOrder,
    CancelOrders {
        count: u32,
    },
    CancelAll,
    CancelMarketOrders,
}

A trading request, carrying whatever its token cost depends on.

Variants

PostOrder

POST /order — always 1 token.

PostOrders

POST /orders — one token per order in the batch.

Fields

count: u32

Number of orders in the batch.

CancelOrder

DELETE /order — always 1 token.

CancelOrders

DELETE /orders — one token per submitted order ID.

Fields

count: u32

Number of order IDs submitted.

CancelAll

DELETE /cancel-all — costs 1 + orders canceled.

The true cost is not knowable client-side; see TradingRequest::cost.

CancelMarketOrders

DELETE /cancel-market-orders — costs 1 + matching orders canceled.

The true cost is not knowable client-side; see TradingRequest::cost.

Implementations

impl TradingRequest

pub fn bucket(self) -> TradingBucket

Which bucket this request draws from.

pub fn cost(self) -> u32

The token cost, as far as the client can know it.

Exact for the four request kinds whose cost is a function of the payload. For CancelAll and CancelMarketOrders the published cost is 1 + orders canceled, and the client does not know how many orders are open — so this returns the floor of 1. Those two can therefore overdraw the real bucket, and a resulting 429 is genuine rather than a client bug.

pub fn cost_is_exact(self) -> bool

Whether this request’s cost is exactly known client-side.

Only requests where this is true can be safely rejected before sending; the rest must be attempted and may come back 429.
