UartEmergencyAccess

Struct UartEmergencyAccess 

Source
pub struct UartEmergencyAccess<'a, E = dyn UartEmergencyTx>
where E: ?Sized,
{ /* private fields */ }
Expand description

Proof that fatal output permanently owns one UART register block.

Dropping this value does not return ownership to normal endpoints. A later emergency formatting call may obtain another access proof from the same gate, while all normal transactions remain excluded until shutdown.
