Struct SerialPortHandle 

pub struct SerialPortHandle { /* private fields */ }

Open USB serial session: sync I/O plus optional background bulk-IN reader.

Implementations

impl SerialPortHandle

pub fn write(&mut self, data: &[u8]) -> Result<usize>

Bulk OUT write. Opens OUT only — IN belongs to the optional Self::start_reader.

pub fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Blocking/synchronous bulk IN read through the driver (not the background reader).

pub fn set_line_config(&mut self, cfg: LineConfig) -> Result<()>

Baud / framing line coding.

pub fn set_flow_control(&mut self, flow: FlowControl) -> Result<()>

pub fn set_dtr(&mut self, value: bool) -> Result<()>

pub fn set_rts(&mut self, value: bool) -> Result<()>

pub fn set_break(&mut self, enabled: bool) -> Result<()>

pub fn purge(&mut self, kind: PurgeKind) -> Result<()>

Clear RX and/or TX driver buffers (host-side purge).

pub fn clear(&mut self, kind: PurgeKind) -> Result<()>

Alias for Self::purge (clear input/output buffers).

pub fn modem_status(&mut self) -> Result<ModemStatus>

Latched modem status lines (CTS/DSR/RI/CD), when the chip reports them.

pub fn close(&mut self)

Stop the bulk-IN reader, close the driver, then mark closed (idempotent).

pub fn start_reader(&mut self) -> Result<()>

Start the background bulk-IN reader (takes ownership of the driver’s IN endpoint).

Call after Self::set_line_config and DTR/RTS on weak OTG / CH340 adapters.

pub fn try_read(&mut self, buf: &mut [u8]) -> Result<usize>

Non-blocking read from the background reader if running; else Self::read.

pub fn stop_reader(&mut self)

Stop and join the background reader without closing the port.

pub fn transport(&self) -> &SharedTransport

Shared transport (for advanced control or re-probe).

Trait Implementations

impl Drop for SerialPortHandle

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
