Module chainlock_transaction

Structs§

AccountingStorageDisabled: Zero-sized storage for debug accounting when DebugAccountingEnabled is false.
AccountingStorageEnabled: Storage for debug accounting when DebugAccountingEnabled is true.
AtomicToken: Atomic storage for a Token.
Bool: Helper type for selecting storage types from compile-time bool constants.
ChainLockTransaction: Environment-independent framework for chain lock transactions.
ChainLockTransactionToken: Zero-sized capability token proving that a transaction of type T is currently active on the calling execution context.
DoneType: Marker type indicating completion of a transaction with no return value.
Option: Wrapper for a transaction state option tag.
SavedState: Saved transaction state returned by ChainLockTransaction::save_state_and_use_reserved_token and ChainLockTransaction::save_state_initial, used to restore an active transaction across context switches.
Token: A transaction generation token used to identify the owning transaction of a ChainLock and arbitrate priority when contention occurs.
TraceStorageDisabled: Zero-sized storage when contention tracing is disabled.
TraceStorageEnabled: Extra state when contention tracing is enabled.

Action: Non-terminal control flow action returned by a transaction attempt closure.
State: Lifecycle state of a ChainLockTransaction.
TransactionResult: Result of a single execution of a transaction attempt closure passed to until_done.

AccountingSelector: Maps a compile-time bool to AccountingStorageEnabled or AccountingStorageDisabled.
AccountingStorage: Storage trait for debug lock accounting in ChainLockTransaction.
ContentionState: Trait for contention state stored inside a ChainLock.
IntoTransactionResult: Trait implemented by return types of closures passed to ChainLockTransaction::until_done.
StateOption: Trait implemented by compile-time state option tags passed to ChainLockTransaction::until_done.
StateSaver: Trait implemented by environment-specific state savers (such as IRQ-save and preempt-disable guards) managed by ChainLockTransaction::until_done.
TraceStorage: Storage trait for contention spin tracing in ChainLockTransaction.
TracingSelector: Maps a compile-time bool to TraceStorageEnabled<C> or TraceStorageDisabled.
Transaction: Trait representing a chain lock transaction type used by ChainLock and ChainLockGuard.
TransactionHooks: Environment-specific hooks required by ChainLockTransaction.

SelectAccounting: Type alias selecting AccountingStorageEnabled when ENABLED is true, or AccountingStorageDisabled when ENABLED is false.
SelectTracing: Type alias selecting TraceStorageEnabled<C> when ENABLED is true, or TraceStorageDisabled when ENABLED is false.
