Struct TouchlessResetWatcher 

pub struct TouchlessResetWatcher { /* private fields */ }

Watcher for the 1200-baud touchless reset.

Track CDC SET_LINE_CODING (baud rate) and SET_CONTROL_LINE_STATE (DTR / RTS) events. When the host opens the port at 1200 baud and then drops DTR, return RescueAction::TriggerDfu so the caller can put the device into serial DFU mode.

The watcher self-suppresses after firing — once TouchlessResetWatcher::fired is true, subsequent events return None until TouchlessResetWatcher::reset is called. In normal operation the BSP’s enter_dfu_serial() diverges so the suppression is moot; it exists for defensive symmetry and testability.

Implementations

impl TouchlessResetWatcher

pub const fn new() -> Self

Construct with the conventional power-on assumption: baud 115200, DTR low (host has not yet opened the port).

pub fn on_line_coding(&mut self, baud: u32) -> RescueAction

Notify of a CDC SET_LINE_CODING request.

pub fn on_control_line_state(&mut self, dtr: bool, _rts: bool) -> RescueAction

Notify of a CDC SET_CONTROL_LINE_STATE request. Only dtr is consulted; rts is accepted for API completeness but ignored, since the Arduino-ecosystem 1200-baud convention is DTR-driven.

pub fn fired(&self) -> bool

pub fn reset(&mut self)

Trait Implementations

impl Debug for TouchlessResetWatcher

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TouchlessResetWatcher

fn default() -> Self

Returns the “default value” for a type.
