Implementations§

Source§

impl TierCache

Source

pub fn new(db: Arc<dyn TierWriter>) -> Result<Self>

Source

pub fn new_with_config( db: Arc<dyn TierWriter>, config: TierCacheConfig, ) -> Result<Self>

Source

pub async fn load_from_db(&self) -> Result<()>

Load all tier configurations from database

Source

pub async fn get_tier(&self, wallet: &WalletAddress) -> Option<UserTierData>

Get tier for wallet (returns default if not found)

Source

pub async fn get_tier_record( &self, wallet: &WalletAddress, ) -> Result<Option<UserTier>>

Source

pub async fn restore_tier_record( &self, wallet: &WalletAddress, previous_tier: Option<&UserTier>, ) -> Result<()>

Source

pub fn get_tier_sync(&self, wallet: &WalletAddress) -> UserTierData

Get tier synchronously (for use in unified_engine) This is non-blocking and returns default if cache is locked or tier not found

Source

fn try_get_from_cache(&self, wallet: &WalletAddress) -> Option<UserTierData>

Source

pub async fn set_tier(&self, update: UserTierUpdate) -> Result<()>

Set or update tier

Source

pub async fn delete_tier(&self, wallet: &WalletAddress) -> Result<()>

Reset tier limits to defaults while preserving the explicit margin mode row.

Source

pub fn is_tier1(&self, wallet: &WalletAddress) -> bool

Check if wallet is tier1 (restricted to long-only)

Source

pub fn is_tier2(&self, wallet: &WalletAddress) -> bool

Check if wallet is tier2 (unrestricted)

Source

pub async fn get_margin_mode( &self, wallet: &WalletAddress, ) -> Result<MarginMode>

Get margin mode for wallet.

This is the async version for use in handlers.

Source

pub async fn get_existing_margin_mode( &self, wallet: &WalletAddress, ) -> Result<Option<MarginMode>>

Get the existing margin mode for a wallet without fabricating a default.

Returns Ok(None) only when no tier row exists. Invalid stored values still fail closed because the persisted margin mode is corrupted.

Source

pub fn get_existing_margin_mode_sync( &self, wallet: &WalletAddress, ) -> Result<Option<MarginMode>>

Get an existing margin mode synchronously without fabricating a default.

Source

pub fn get_margin_mode_sync(&self, wallet: &WalletAddress) -> Result<MarginMode>

Get margin mode synchronously (for use in unified_engine).

Non-blocking and fail-closed if the cache is locked. Missing rows intentionally resolve to Standard; see get_margin_mode.

Source

pub async fn set_margin_mode( &self, wallet: &WalletAddress, mode: MarginMode, ) -> Result<i64>

Set margin mode for a wallet.

Creates the tier entry if it doesn’t exist. Returns the new version for use in event messages.

Source

pub async fn insert_margin_mode_if_missing( &self, wallet: &WalletAddress, mode: MarginMode, ) -> Result<Option<i64>>

Create a margin mode row if one does not already exist.

Returns Some(version) when a row was inserted. Existing rows are left unchanged so callers can safely use this for bootstrap paths.

Source

pub fn get_all_margin_modes_sync( &self, ) -> Result<HashMap<WalletAddress, MarginMode>>

Extract all wallet margin modes from the cache.

Used at startup to seed engine-owned wallet_margin_modes so the engine never needs the fallback try_read() path.

Source

pub fn get_all_trading_limits_sync( &self, ) -> Result<HashMap<WalletAddress, TradingLimits>, String>

Extract all wallet trading limits from the cache.

Returns an error if the lock cannot be acquired (e.g. contention during engine seed). Callers must not silently default to empty.

Source

pub fn get_all_tiers_sync( &self, ) -> Result<HashMap<WalletAddress, String>, String>

Extract all wallet tier strings from the cache.

Returns an error if the lock cannot be acquired.

Source

pub fn is_standard_margin(&self, wallet: &WalletAddress) -> Result<bool>

Check if wallet is in Standard margin mode.

Source

pub fn is_portfolio_margin(&self, wallet: &WalletAddress) -> Result<bool>

Check if wallet is in Portfolio margin mode.

Source

pub async fn apply_margin_mode_update( &self, wallet: WalletAddress, mode: MarginMode, version: i64, )

Apply a margin mode update from the event bus (for cross-process cache sync).

This is called when we receive a TierUpdate message. Only applies the update if the version is newer than the cached version.

Source

pub async fn get_version(&self, wallet: &WalletAddress) -> i64

Get the current version for a wallet’s tier configuration.

Source

pub fn get_trading_limits(&self, wallet: &WalletAddress) -> TradingLimits

Get trading limits for a wallet.

Returns the wallet’s configured limits, or defaults if not found.

Source

pub async fn get_trading_limits_async( &self, wallet: &WalletAddress, ) -> TradingLimits

Get trading limits asynchronously.

Source

pub fn exceeds_open_orders_limit( &self, wallet: &WalletAddress, current_count: usize, ) -> bool

Check if the number of open orders exceeds the limit. Returns true if the limit is exceeded. Returns false if limit is negative (unlimited).

Source

pub fn exceeds_positions_limit( &self, wallet: &WalletAddress, current_count: usize, ) -> bool

Check if the number of positions exceeds the limit. Returns true if the limit is exceeded. Returns false if limit is -1 (unlimited).

Source

pub fn default_trading_limits(&self) -> TradingLimits

Source

fn trading_limits_from_tier(&self, tier: &UserTier) -> TradingLimits

Source

pub async fn set_margin_mode_in_memory( &self, wallet: &WalletAddress, mode: MarginMode, )

Set the margin mode for a wallet in the in-memory cache only (no DB write). Use this in tests that need to simulate PM vs SM accounts.
