Struct Actions 

pub struct Actions { /* private fields */ }

Actions buffer - orders to send.

Implementations

impl Actions

pub const fn new() -> Self

pub fn clear(&mut self)

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn is_full(&self) -> bool

pub fn buy(&mut self, order_id: u64, qty_1e8: i64, px_1e9: u64) -> bool

Place a limit buy order (GTC - Good Till Canceled).

pub fn sell(&mut self, order_id: u64, qty_1e8: i64, px_1e9: u64) -> bool

Place a limit sell order (GTC - Good Till Canceled).

pub fn order( &mut self, order_id: u64, side: i8, qty_1e8: i64, px_1e9: u64, ) -> bool

Place limit order with explicit side (1=buy, -1=sell).

pub fn market_buy(&mut self, order_id: u64, qty_1e8: i64) -> bool

Place a market buy order (fills immediately).

pub fn market_sell(&mut self, order_id: u64, qty_1e8: i64) -> bool

Place a market sell order (fills immediately).

pub fn ioc_buy(&mut self, order_id: u64, qty_1e8: i64, px_1e9: u64) -> bool

Place IOC buy - fills available liquidity, cancels unfilled portion.

pub fn ioc_sell(&mut self, order_id: u64, qty_1e8: i64, px_1e9: u64) -> bool

Place IOC sell - fills available liquidity, cancels unfilled portion.

pub fn fok_buy(&mut self, order_id: u64, qty_1e8: i64, px_1e9: u64) -> bool

Place FOK buy - must fill entire quantity or rejected.

pub fn fok_sell(&mut self, order_id: u64, qty_1e8: i64, px_1e9: u64) -> bool

Place FOK sell - must fill entire quantity or rejected.

pub fn post_only_buy( &mut self, order_id: u64, qty_1e8: i64, px_1e9: u64, ) -> bool

Place a post-only buy order (maker only, rejected if would cross).

pub fn post_only_sell( &mut self, order_id: u64, qty_1e8: i64, px_1e9: u64, ) -> bool

Place a post-only sell order (maker only, rejected if would cross).

pub fn order_typed( &mut self, order_id: u64, side: i8, qty_1e8: i64, px_1e9: u64, order_type: u8, ) -> bool

Place order with explicit type.

pub fn cancel(&mut self, order_id: u64) -> bool

Cancel an order.

pub fn cancel_all(&mut self, state: &AlgoState)

Cancel all open orders.

pub fn amend( &mut self, order_id: u64, new_qty_1e8: i64, new_px_1e9: u64, ) -> bool

Amend an existing order’s price and/or quantity.

Uses is_cancel = ACTION_AMEND (2). The venue performs an atomic edit — the order keeps its ID and (when only qty decreases) its queue position.

Returns false if the actions buffer is full.

pub fn amend_on( &mut self, venue_id: u8, order_id: u64, new_qty_1e8: i64, new_px_1e9: u64, ) -> bool

Amend an existing order on a specific venue.

pub fn buy_on( &mut self, venue_id: u8, order_id: u64, qty_1e8: i64, px_1e9: u64, ) -> bool

Place a limit buy on a specific venue. venue_id is a VenueId value from NbboSnapshot.venue_ids[].

pub fn sell_on( &mut self, venue_id: u8, order_id: u64, qty_1e8: i64, px_1e9: u64, ) -> bool

Place a limit sell on a specific venue.

pub fn ioc_buy_on( &mut self, venue_id: u8, order_id: u64, qty_1e8: i64, px_1e9: u64, ) -> bool

Place an IOC buy on a specific venue.

pub fn ioc_sell_on( &mut self, venue_id: u8, order_id: u64, qty_1e8: i64, px_1e9: u64, ) -> bool

Place an IOC sell on a specific venue.

pub fn order_on_venue( &mut self, venue_id: u8, order_id: u64, side: i8, qty_1e8: i64, px_1e9: u64, order_type: u8, ) -> bool

Place a venue-targeted order with explicit side and order type. Used by the runtime to replay actions read from WASM memory.

pub fn clear_at(&mut self, idx: usize)

Zero out an action at index (marks as no-op). Used by risk engine to neutralize rejected actions in-place.

pub fn get(&self, idx: usize) -> Option<&Action>

pub fn iter(&self) -> impl Iterator<Item = &Action>

Trait Implementations

impl Default for Actions

fn default() -> Self

Returns the “default value” for a type.
