Struct spectrusty_formats::tap::TapChunkPulseIter

pub struct TapChunkPulseIter<R> {
    pub auto_next: bool,
    // some fields omitted
}

Implements an iterator of T-state pulse intervals over the TapChunkReader. See also: ReadEncPulseIter.

Fields

auto_next: bool

Determines if a next chunk should be processed after the previous one ends.

• false to start iterating over pulses of the next chunk a TapChunkRead::next_chunk method should be called first. Until then the Iterator::next will return None.
• true the next chunk will be processed automatically and a single pulse of the interval of PAUSE_PULSE_LENGTH T-states is emitted before lead pulses of the next chunk.

Implementations
