Implementations§

Source§

impl KeyboardBuffer

Source

const fn new() -> Self

Source

pub fn push(&self, ch: u8)

Called exclusively from IRQ context (IF=0 already).

Source

pub fn pop(&self) -> Option<u8>

Called from task context. Interrupts disabled before lock acquisition.

Source

pub fn has_data(&self) -> bool

Called from task context. Same interrupt-disable discipline as pop.
