Records block against the account bound to this control.
The first cause for an account wins, so recording a block against an already-blocked account is a no-op.
Throws InternalError when a panic has poisoned the module,
LifecycleError when the owning transaction has already been finalized,
or ParamError when the block code is not recognized.
Per-account kill-switch block handle scoped to one pre-trade transaction.
Obtained from a context's
accountControl. Callingblockrecords a block against the bound account. The handle is valid only within the owning request's pre-trade processing (through commit or rollback); once invalidated, further calls throw aLifecycleErrorrather than recording against a completed transaction.A panic abandons the operation without invalidating its token, so the handle also rejects every call once a module panic has poisoned the module.
