Enum CommandFailure 

pub enum CommandFailure {
    InvalidSequenceNumber {
        expected_sequence_number: SequenceNumber,
        received_sequence_number: SequenceNumber,
    },
    InvalidTimestamp {

    OrderNotFound,
}

Reason for the command execution failure

Variants

InvalidSequenceNumber

The sequence number of the command is invalid This happens when the command is received out of order

Fields

expected_sequence_number: SequenceNumber

The expected sequence number

received_sequence_number: SequenceNumber

The received sequence number

InvalidTimestamp

The timestamp of the command is invalid This happens when the command is received before the last seen timestamp

Fields

last_seen_timestamp: Timestamp

The last seen timestamp

received_timestamp: Timestamp

The received timestamp

InvalidCommand(CommandError)

The command is invalid This happens when the command violates the invariants of a command

OrderNotFound

The order was not found in the order book

Trait Implementations

impl Clone for CommandFailure

fn clone(&self) -> CommandFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommandFailure

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CommandFailure

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CommandFailure

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

Formats the value using the given formatter.

impl PartialEq for CommandFailure

fn eq(&self, other: &CommandFailure) -> 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.

impl Serialize for CommandFailure

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CommandFailure
