Struct L2TxAttributes 

pub struct L2TxAttributes {
    pub integrator_account_index: u64,
    pub integrator_taker_fee: u32,
    pub integrator_maker_fee: u32,
    pub skip_nonce: u8,
    pub cancel_all_market_index: Option<i64>,
    pub self_trade_behavior_mode: Option<LighterSelfTradeBehaviorMode>,
    pub self_trade_equality_mode: Option<LighterSelfTradeEqualityMode>,
}

Per-transaction L2 attributes.

Default-valued attributes do not contribute to the signed hash. Explicit self-trade defaults are still emitted in JSON and count toward the four-attribute limit.

Fields

integrator_account_index: u64

Integrator account index.

integrator_taker_fee: u32

Integrator taker fee in fee-tick units.

integrator_maker_fee: u32

Integrator maker fee in fee-tick units.

skip_nonce: u8

1 to instruct the sequencer to skip nonce bookkeeping for this tx.

cancel_all_market_index: Option<i64>

Cancel-all market attribute; None or 255 does not contribute to the hash. CancelAllOrdersTxInfo does not carry this attribute.

self_trade_behavior_mode: Option<LighterSelfTradeBehaviorMode>

Self-trade action; None leaves the venue default in force.

self_trade_equality_mode: Option<LighterSelfTradeEqualityMode>

Self-trade account scope; None leaves the venue default in force.

Implementations

impl L2TxAttributes

pub fn is_empty(&self) -> bool

Returns true when no attribute contributes to the hash.

Explicit nil values can still occupy JSON entries. Encoders use only the body hash when this returns true, matching upstream IsEmpty.

pub fn validate(&self) -> Result<()>

Checks attribute capacity and the venue’s self-trade restrictions.

Errors

Returns an error if:

• The transaction exceeds the attribute limit.
• The cancel-all market index is invalid.
• Non-default self-trade modes combine with non-zero integrator fees.
• Reduce behavior combines with master-account equality.
