Struct ModbusBuffer 

pub struct ModbusBuffer<const CAPACITY: usize> { /* private fields */ }

Implementations

impl<const CAPACITY: usize> ModbusBuffer<CAPACITY>

pub fn new() -> Self

Creates a new ModbusBuffer with specified constants.

pub fn min_frame_len(self, min_frame_len: usize) -> Self

Sets the minimum frame length required to detect a Modbus frame, excluding CRC.

pub fn max_frame_len(self, max_frame_len: usize) -> Self

Sets the maximum frame length that can be detected, excluding CRC.

pub fn overwrite(self, overwrite: bool) -> Self

Configures whether to overwrite old data if the buffer is full or to panic.

pub fn push(&mut self, item: u8)

Adds an item to the buffer, handling overflow based on the overwrite flag.

pub fn pop(&mut self) -> Option<u8>

Removes and returns the oldest element from the buffer if available.

pub fn len(&self) -> usize

Returns the current number of elements in the buffer.

pub fn is_empty(&self) -> bool

Returns true if the buffer is empty.

pub fn is_full(&self) -> bool

Returns true if the buffer is full.

pub fn try_decode_frame(&mut self, buffer: &mut [u8; CAPACITY]) -> Option<usize>

Attempts to decode a Modbus frame from the internal buffer and copies it into the provided buffer if successful.

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

Formats the value using the given formatter.
