Struct RegisterPoints 

pub struct RegisterPoints { /* private fields */ }

A local cache of 16-bit register values mapped to their Modbus addresses.

Use apply_read to merge values returned by ModbusClient::read_holding_registers.

Implementations

impl RegisterPoints

pub fn new(start_address: u16, count: usize) -> Self

Create a new register cache with count registers starting at start_address, all initially 0.

pub fn from_values(start_address: u16, values: Vec<u16>) -> Self

Create a register cache from existing values.

pub fn start_address(&self) -> u16

The starting Modbus address of this cache.

pub fn len(&self) -> usize

The number of registers in this cache.

pub fn is_empty(&self) -> bool

Returns true if the cache contains no registers.

pub fn values(&self) -> &[u16]

View the raw register values as a slice.

pub fn get(&self, address: u16) -> Option<u16>

Get the register value at the given Modbus address, or None if out of range.

pub fn set(&mut self, address: u16, value: u16) -> Result<(), ClientError>

Set the register value at the given Modbus address.

pub fn apply_read( &mut self, start_address: u16, values: &[u16], ) -> Result<(), ClientError>

Merge a batch of read values into this cache at the given start address.

Trait Implementations

impl Clone for RegisterPoints

fn clone(&self) -> RegisterPoints

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RegisterPoints

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

Formats the value using the given formatter.

impl PartialEq for RegisterPoints

fn eq(&self, other: &RegisterPoints) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
