Enum ReadCode 

pub enum ReadCode {
    Basic,
    Regular,
    Extended,
    Specific,
}

Types Represents the Modbus read device identification access type.

Used to specify the type of information to retrieve from a device during a “Read Device Identification” Modbus function (0x2B / 0x0E).

Variants

Basic

Basic identification (stream access). Corresponds to value 0x01. Returns a minimal set of identification data.

Regular

Regular identification (stream access). Corresponds to value 0x02. Returns additional identification beyond basic.

Extended

Extended identification (stream access). Corresponds to value 0x03. Returns the most comprehensive set of device info.

Specific

Specific identification (individual access). Corresponds to value 0x04. Used to retrieve a specific object by ID.

Implementations

impl ReadCode

pub const fn try_from_value(value: u8) -> Option<Self>

Attempts to convert a raw u8 value to a ReadCode.

Parameters

• value: The raw byte representing the read code.

Returns

• Some(ReadCode) if the value is valid.
• None otherwise.

pub const fn value(self) -> u8

Returns the u8 representation of the current ReadCode variant.

Returns

A byte corresponding to the Modbus function read code.

Trait Implementations

impl Clone for ReadCode

fn clone(&self) -> ReadCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadCode

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

Formats the value using the given formatter.

impl PartialEq for ReadCode

fn eq(&self, other: &ReadCode) -> 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.
