Struct OrderOrigin 

pub struct OrderOrigin {
    pub scope: EnumValue<OrderOriginScope>,
    pub trigger_type: EnumValue<OrderTriggerType>,
    pub trigger_id: Option<u64>,
    pub parent_order_id: Option<u64>,
    pub child_seq: u32,
    /* private fields */
}

OrderOrigin explains why an order exists and where it came from.

Population rules:

• direct/manual orders: scope=DIRECT; trigger fields unset/unspecified.
• attached children: scope=ATTACHED_RISK; parent_order_id is set.
• standalone trigger children: scope=STANDALONE_TRIGGER.
• child_seq is set for multi-child strategies (for example TWAP/LADDER).

Fields

scope: EnumValue<OrderOriginScope>

Broad class describing how the order was created.

Field 1: scope

trigger_type: EnumValue<OrderTriggerType>

Trigger strategy that created this order, or unspecified for direct orders.

Field 2: trigger_type

trigger_id: Option<u64>

Trigger identifier when the order was created by a trigger.

Field 3: trigger_id

parent_order_id: Option<u64>

Parent order ID for attached-risk child orders.

Field 4: parent_order_id

child_seq: u32

Child sequence number for multi-child trigger strategies. Zero when not applicable.

Field 5: child_seq

impl Message for OrderOrigin

fn compute_size(&self, _cache: &mut SizeCache) -> u32

Returns the total encoded size in bytes.

The result is a u32; the protobuf specification requires all messages to fit within 2 GiB (2,147,483,647 bytes), so a compliant message will never overflow this type.

Processes a single already-decoded tag and its associated field data from buf.

fn clear(&mut self)

Clear all fields to their default values.

fn encode(&self, buf: &mut impl BufMut)

Compute size, then write. This is the primary encoding API.

fn encode_with_cache(&self, cache: &mut SizeCache, buf: &mut impl BufMut)

Encode using a caller-supplied SizeCache, for reuse across many encodes in a hot loop. Clears the cache first.

fn encoded_len(&self) -> u32
