Struct LogMessage 

pub struct LogMessage { /* private fields */ }

Fixed-size (255 byte) log/command message buffer with USB packet fragmentation support.

This struct provides a fixed-size buffer for log messages that can be efficiently transmitted over USB by fragmenting into smaller packets. Messages longer than the buffer capacity are automatically truncated with an ellipsis indicator.

Implementations

impl LogMessage

pub fn new() -> Self

Create an empty message buffer.

pub fn packet_count(&self) -> usize

Number of 64-byte USB packets required to send this message.

Returns the minimum number of USB packets needed to transmit the entire message content.

pub fn as_packet_bytes(&self, packet_index: usize) -> &[u8]

Slice for a specific packet index (0-based) containing that chunk.

Returns the bytes for the specified packet index. The last packet may be shorter than PACKET_SIZE if the message doesn’t divide evenly.

Trait Implementations

impl Write for LogMessage

fn write_str(&mut self, s: &str) -> FmtResult

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
