Enum DataType 

pub enum DataType {
    Counter,
    SensorReading {
        sensor_count: u32,
    },
    Generic,
}

Specifies the type of synthetic data to generate.

Each variant produces elements with different schemas and behaviors. See the crate-level documentation for detailed examples of each type.

Variants

Counter

Generates sequential counter values (1, 2, 3, …).

Each event is an INSERT with a unique element ID (counter_1, counter_2, etc.). Properties include value (the counter) and timestamp.

SensorReading

Generates simulated IoT sensor readings.

Produces temperature (20.0-30.0) and humidity (40.0-60.0) values from a pool of simulated sensors. The first reading for each sensor is an INSERT; subsequent readings for the same sensor are UPDATEs.

Fields

sensor_count: u32

Number of distinct sensors to simulate. Must be at least 1. Sensor IDs will be in range [0, sensor_count).

Generic

Generates generic data with random values (default).

Each event is an INSERT with a unique element ID (generic_1, generic_2, etc.). Properties include value (random i32), message, and timestamp.

Implementations

impl DataType

pub fn sensor_reading(sensor_count: u32) -> Self

Creates a SensorReading data type with the specified sensor count.

Arguments

• sensor_count - Number of distinct sensors to simulate (must be ≥ 1)

Example

use drasi_source_mock::DataType;

let data_type = DataType::sensor_reading(10);
assert_eq!(data_type.sensor_count(), Some(10));

pub fn sensor_count(&self) -> Option<u32>

Returns the sensor count if this is a SensorReading variant.

Returns

• Some(count) for SensorReading variants
• None for Counter and Generic variants

Trait Implementations

impl Clone for DataType

fn clone(&self) -> DataType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataType

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

Formats the value using the given formatter.

impl Default for DataType

fn default() -> DataType

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DataType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DataType

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

Formats the value using the given formatter.

impl PartialEq for DataType

fn eq(&self, other: &DataType) -> 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 DataType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DataType

impl StructuralPartialEq for DataType
