Enum Capability 

#[non_exhaustive]
pub enum Capability {
    StopOrders,
    PostOnly,
    ReduceOnly,
    Ioc,
    Fok,
    PublicFeed,
    PrivateFeed,
    OrderTracking,
}

Optional adapter capabilities, queried via ExchangeClient::supports.

The framework consults this to degrade gracefully when an adapter doesn’t implement a feature an Order or strategy requests — e.g. rejecting an order with Order.stop = Some(...) against an adapter that returns false for Capability::StopOrders rather than silently dropping the attachment.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

StopOrders

Adapter accepts Order.stop and translates to native stop orders.

PostOnly

Adapter rejects post-only orders that would cross the book as taker.

ReduceOnly

Adapter honours Order.reduce_only.

Ioc

Adapter supports OrderKind::Ioc.

Fok

Adapter supports OrderKind::Fok.

PublicFeed

Adapter can stream a public market-data feed alongside trading. Most do; spot-only HTTP adapters may not.

PrivateFeed

Adapter pushes fill / order-update events on a private feed.

OrderTracking

Adapter implements ExchangeClient::get_open_orders and ExchangeClient::cancel_order — required for resting-order tracking, TTL cancellation, and reconnect reconciliation.

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Capability

impl Debug for Capability

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

Formats the value using the given formatter.

impl Eq for Capability

impl Hash for Capability

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Capability

fn eq(&self, other: &Capability) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
