template <typename IoProvider>
void Init (IoProvider & io)

uart::KernelDriver UartDriver API

Each method is a template parameterized by an IoProvider type for

accessing the hardware registers so that real Driver types can be used

with hwreg::Mock in tests independent of actual hardware access. The

null Driver never uses the `io` arguments.

template <typename IoProvider>
bool TxReady (IoProvider & io)

Return true if Write can make forward progress right now.

Defined at line 86 of file ../../zircon/system/ulib/uart/include/lib/uart/null.h

template <typename IoProvider, typename It1, typename It2>
auto Write (IoProvider & io, bool , It1 it, const It2 & end)

This is called only when TxReady() has just returned true. Advance

the iterator at least one and as many as is convenient but not past

end, outputting each character before advancing.

template <typename IoProvider>

void EnableTxInterrupt (IoProvider & io)

Enable transmit interrupts so Interrupt will be called when TxReady().

Defined at line 106 of file ../../zircon/system/ulib/uart/include/lib/uart/null.h
