Enum DeriveOrderCancelReason 

pub enum DeriveOrderCancelReason {
    Empty,
    UserRequest,
    MmpTrigger,
    InsufficientMargin,
    SignedMaxFeeTooLow,
    CancelOnDisconnect,
    IocOrMarketPartialFill,
    SessionKeyDeregistered,
    SubaccountWithdrawn,
    Compliance,
    TriggerFailed,
    ValidationFailed,
    AlgoCompleted,
    PostOnlyCrossMarket,
}

Cancel reason attached to a cancelled order. Empty string corresponds to no reason (order is still open or finished by another transition).

ValidationFailed is present in the SDK enum but absent from the public JSON schema; included here for round-trip fidelity against SDK responses.

Variants

Empty

No cancel reason (open or finished without cancellation).

UserRequest

Explicit cancel via private/cancel*.

MmpTrigger

Market Maker Protection tripped.

InsufficientMargin

Margin check failed at matching.

SignedMaxFeeTooLow

Signed max_fee is below the venue’s current required fee.

CancelOnDisconnect

WS disconnect cancelled the session with cancel-on-disconnect enabled.

IocOrMarketPartialFill

Remainder of an IOC or market order auto-cancelled.

SessionKeyDeregistered

Signing session key was deregistered.

SubaccountWithdrawn

Subaccount fully withdrawn.

Compliance

Cancelled by compliance action.

TriggerFailed

Trigger worker could not submit the child order.

ValidationFailed

Pre-engine validation failure (SDK-only, not in the public schema).

AlgoCompleted

Algorithmic parent completed after finishing its slices.

PostOnlyCrossMarket

Post-only order would cross the market.

fn clone(&self) -> DeriveOrderCancelReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DeriveOrderCancelReason

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<DeriveOrderCancelReason, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for DeriveOrderCancelReason

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