Struct Ymodem 

pub struct Ymodem { /* private fields */ }

YMODEM protocol handler for file transfers.

Implements the YMODEM protocol for sending files over serial connections. Supports both CRC16 and checksum modes.

Implementations

impl Ymodem

pub fn new(crc_mode: bool) -> Self

Creates a new YMODEM sender.

Arguments

• crc_mode - Whether to start in CRC16 mode (true) or checksum mode (false)

pub fn send<D: Write + Read, F: Read>( &mut self, dev: &mut D, file: &mut F, name: &str, size: usize, on_progress: impl Fn(usize), ) -> Result<()>

Sends a file over the YMODEM protocol.

Arguments

• dev - The device implementing Read + Write (serial stream)
• file - The readable file stream
• name - File name reported to the receiver
• size - File size in bytes
• on_progress - Callback invoked with the total bytes sent so far

Errors

Returns any I/O error from the underlying device or file stream.
