Enum NotPlacedReason 

#[non_exhaustive]
pub enum NotPlacedReason {
    NotSent(ConnectivityError),
    UnknownToVenue,
    CancelFailed {
        cancel: ClientOrderId,
    },
}

How an order is known not to have been placed.

Carried by OrderError::NotPlaced.

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.

NotSent(ConnectivityError)

The open request never left the client, because the connection failed before the send: refused, unresolved, or a closed channel to a simulated venue.

A client returns this only where the failure provably came before the send. A failure it cannot place is OrderError::Connectivity.

UnknownToVenue

The open’s outcome was unknown, and the venue, asked about the order by its client order id several times since, does not know it.

The engine’s ExecutionManager reports this, after the lookups its policy sets out.

CancelFailed

The open was held back behind the cancels of its CancelThenOpen group, and was never sent because one of them failed.

cancel is the client order id of the first cancel in the group whose answer was an error, a timeout included. That cancel’s own answer says why it failed. Only a group whose OnCancelFailure is DropOpens drops its opens.

Fields

cancel: ClientOrderId

The client order id of the first cancel in the group that failed.
