Function libmodbus_rs::set_bits_from_bytes

pub fn set_bits_from_bytes(
    dest: &mut [u8], 
    index: u32, 
    num_bit: u16, 
    bytes: &[u8]
)

set_bits_from_bytes - set many bits from an array of bytes

The set_bits_from_bytes() function shall set many bits from a single byte. All 8 bits from the byte value will be written to dest array starting at index position.

Parameters

dest - destination slice index - starting position where the bit should written num_bit - how many bits should written bytes - All the bits of the bytes parameter, read from the first position of the vec bytes are written as bits in the dest vec, starting at position index

Examples

use libmodbus_rs::{Modbus, ModbusMapping, ModbusTCP};
let modbus = Modbus::new_tcp("127.0.0.1", 1502).unwrap();
let modbus_mapping = ModbusMapping::new(5, 5, 5, 5).unwrap();

assert_eq!(modbus_mapping.get_input_bits_mut(), [0u8, 0, 0, 0, 0]);
libmodbus_rs::set_bits_from_bytes(modbus_mapping.get_input_bits_mut(), 0, 2, &[0b0000_1111]);
assert_eq!(modbus_mapping.get_input_bits_mut(), [1u8, 1, 0, 0, 0]);
