Struct TypedDataPoint 

pub struct TypedDataPoint<T>
where
    T: DataPointType,
{
    pub id: String,
    pub name: String,
    pub description: String,
    pub access: AccessMode,
    pub units: Option<String>,
    pub min_value: Option<f64>,
    pub max_value: Option<f64>,
    pub default_value: Option<T>,
    /* private fields */
}

A type-safe data point reference.

This struct wraps a data point with compile-time type information, ensuring type safety when reading and writing values.

Fields

id: String

Point ID within the device.

name: String

Human-readable name.

description: String

Description.

access: AccessMode

Access mode.

units: Option<String>

Engineering units.

min_value: Option<f64>

Minimum value (for numeric types).

max_value: Option<f64>

Maximum value (for numeric types).

default_value: Option<T>

Default value.
