Enum ModbusTypedValue 

pub enum ModbusTypedValue {
    Bool(bool),
    I16(i16),
    U16(u16),
    I32(i32),
    U32(u32),
    F32(f32),
    F64(f64),
    Str(String),
}

Strongly-typed value decoded from a Modbus register array.

This is a richer type than crate::mapping::ModbusValue; it preserves the exact Rust primitive and supports lossless f64 conversion for arithmetic / scaling.

Variants

Bool(bool)

Boolean decoded from a coil or discrete input

I16(i16)

Signed 16-bit integer (single register)

U16(u16)

Unsigned 16-bit integer (single register)

I32(i32)

Signed 32-bit integer (two registers)

U32(u32)

Unsigned 32-bit integer (two registers)

F32(f32)

IEEE-754 single-precision float (two registers)

F64(f64)

IEEE-754 double-precision float (four registers)

Str(String)

ASCII string decoded from N register pairs

Implementations

impl ModbusTypedValue

pub fn as_f64(&self) -> Option<f64>

Convert to f64 for scaling and range checks.

Returns None for string values which cannot be meaningfully converted.

pub fn scale(&self, scale_factor: f64, offset: f64) -> Option<f64>

Apply a linear scale factor and additive offset, returning an f64.

Formula: physical = raw * scale_factor + offset

Returns None when the value cannot be converted to f64 (strings).

pub fn type_name(&self) -> &'static str

Name of the type as a static string.

Trait Implementations

impl Clone for ModbusTypedValue

fn clone(&self) -> ModbusTypedValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModbusTypedValue

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

Formats the value using the given formatter.

impl Display for ModbusTypedValue

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

Formats the value using the given formatter.

impl PartialEq for ModbusTypedValue

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