Variants

Nop(ReadHandlerResult<u8>)

No Operation - dummy callback that evaluates to a fixed constant return value.

Function(fn(_: Isolated, _: SerialPortIdentity, _: u8, _: Option<*const dyn Any>) -> ReadHandlerResult<u8>)

A function/closure callback. This will be called when the interrupt service routine needs it; the function signature is context dependent, however the last parameter will always be an Option<&'static dyn Any> user-data field, which will be given a None value. The first parameter must be an isolation token (avr_oxide::concurrency::Isolated)

WithData(fn(_: Isolated, _: SerialPortIdentity, _: u8, _: Option<*const dyn Any>) -> ReadHandlerResult<u8>, *const dyn Any)

A function/closure callback. This will be called when the interrupt service routine needs it; the function signature is context dependent, however the last parameter will always be an Option<&'static dyn Any> user-data field, into which the given data will be passed as Some() value. The first parameter must be an isolation token (avr_oxide::concurrency::Isolated)
