Struct pir_8_emu::ReadWriteMarker

pub struct ReadWriteMarker { /* fields omitted */ }

Marker for wrapper types that need to track when they were read from/written to.

Examples

let marker = ReadWriteMarker::new();

assert_eq!(marker.was_read(), false);
assert_eq!(marker.was_written(), false);

marker.read();
assert_eq!(marker.was_read(), true);

let mut marker = marker;
marker.written();
assert_eq!(marker.was_written(), true);

marker.reset();
assert_eq!(marker.was_read(), false);
assert_eq!(marker.was_written(), false);

Methods

impl ReadWriteMarker

pub fn new() -> ReadWriteMarker

Create a new unread and unwritten marker.

pub fn read(&self)

Mark this marker read.

pub fn written(&mut self)

pub fn was_read(self) -> bool

Check if this marker was marked read.

pub fn was_written(self) -> bool

Check if this marker was marked written.

pub fn reset(&mut self)

Reset the marker to its original unread and unwritten state.
