Enum Processor 

pub enum Processor {
    Median(MedianProcessor),
    WeightedMedian(WeightedMedianProcessor),
}

Represents different strategies for processing source data into a signal value.

The Processor enum encapsulates different algorithms for combining multiple input values from various sources into a single output value. Each variant contains its own configuration parameters.

Variants

• Median - Computes the median of the input values
• WeightedMedian - Computes a weighted median based on configured weights

Examples

Creating a median processor:

use bothan_lib::registry::processor::{Processor, median::MedianProcessor};
use serde_json::json;

// Create a processor from JSON
let json_data = json!({
    "function": "median",
    "params": {
        "min_source_count": 3
    }
});

let processor: Processor = serde_json::from_value(json_data).unwrap();
assert_eq!(processor.name(), "median");

Using a processor:

use bothan_lib::registry::processor::{Processor, median::MedianProcessor};
use rust_decimal::Decimal;

// Create a median processor that requires at least 3 sources
let processor = Processor::Median(MedianProcessor { min_source_count: 3 });

// Process some data
let data = vec![
    ("source1".to_string(), Decimal::new(100, 0)),
    ("source2".to_string(), Decimal::new(200, 0)),
    ("source3".to_string(), Decimal::new(300, 0)),
];

let result = processor.process(data).unwrap();
assert_eq!(result, Decimal::new(200, 0));

Variants

Median(MedianProcessor)

Median processor that computes the median of input values.

WeightedMedian(WeightedMedianProcessor)

Weighted median processor that applies weights to input values.

Implementations

impl Processor

pub fn name(&self) -> &str

Returns the name of the processor.

This method returns a string identifier for the processor type, which can be used for logging, debugging, or serialization purposes.

pub fn process( &self, data: Vec<(String, Decimal)>, ) -> Result<Decimal, ProcessError>

Processes input data into a single output value.

This method applies the processor’s algorithm to the input data to produce a single output value. The input data consists of pairs of source identifiers and their corresponding values.

Errors

Returns a ProcessError if the processing operation fails, such as when:

• There are insufficient data points
• The data does not meet the processor’s requirements
• A mathematical error occurs during processing

Trait Implementations

impl<'__de, __Context> BorrowDecode<'__de, __Context> for Processor

fn borrow_decode<__D: BorrowDecoder<'__de, Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given BorrowDecode.

impl Clone for Processor

fn clone(&self) -> Processor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Processor

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

Formats the value using the given formatter.

impl<__Context> Decode<__Context> for Processor

fn decode<__D: Decoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given Decode.

impl<'de> Deserialize<'de> for Processor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for Processor

fn encode<__E: Encoder>(&self, encoder: &mut __E) -> Result<(), EncodeError>

Encode a given type.

impl PartialEq for Processor

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
