Struct PvRange 

pub struct PvRange {
    pub high: f32,
    pub low: f32,
}

PV scale range, read once before the test starts (PvSH/PvSL in the legacy app’s ReadInitialOPCvalues) – distinct from MvRange, used only to express the oscillation amplitude as a percentage in core-tuning-math::measure_oscillation.

Fields

high: f32

low: f32

Implementations

impl PvRange

pub fn new(high: f32, low: f32) -> Result<Self, RangeError>

Validates a PV range read from an untrusted source (a live OPC DA tag, a CLI flag override). Rejects a non-finite bound (NaN/infinite) or a zero span (high == low, which would make measure_oscillation’s amplitude-as-a-percentage-of-range calculation divide by zero). Unlike MvRange, the two bounds are not required to be in low < high order – only genuinely distinct – since the PV range is used solely as a span magnitude here, not as an inequality bound the way the MV range is in clamp_relay_amplitude.

Trait Implementations

impl Clone for PvRange

fn clone(&self) -> PvRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PvRange

impl Debug for PvRange

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PvRange

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PvRange

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

impl Serialize for PvRange

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
