Struct Receiver 

pub struct Receiver { /* private fields */ }

Reassembles received events into digits.

The whole job is reporting each keypress exactly once. A tone arrives as many packets and its end arrives three times, so a receiver that reports what it receives reports every digit four or more times — which, for a caller entering a PIN, is a wrong PIN.

Implementations

impl Receiver

pub fn new() -> Self

A receiver with nothing in progress.

pub fn push(&mut self, timestamp: u32, event: &Event) -> Option<Digit>

Feed one telephone-event packet.

Returns the digit when the tone ends, and None while it is still sounding or if this packet is a repeat of an end already reported.

pub fn in_progress(&self) -> Option<Digit>

The digit currently sounding, if any.
