Module models

Core domain models for the flow trading system.

This module contains the fundamental data structures that represent the domain entities.

The models in this module are primarily data structures with minimal business logic, following the principles of the hexagonal architecture to separate domain entities from their persistence and processing implementations.

Structs

ConstantCurve

A representation of a flat demand curve supporting interval, half-line, and full-line trading domains

ConstantCurveDto

A DTO to ensure that we always validate when we deserialize from an untrusted source

DateTimeRangeQuery

A query type for dealing with datetime ranges

DateTimeRangeResponse

The paginated response to a datetime query

DemandGroup

A wrapper around an implementation of a HashMap, with values of f64.

DemandRecord

Represents a demand entity in the flow trading system.

Map

A wrapper around an implementation of a HashMap, defaulting to values of f64.

OutcomeRecord

A timestamped record of an outcome from batch processing.

Point

A representation of a point for use in defining piecewise-linear curves

PortfolioRecord

Represents a portfolio entity in the flow trading system.

ProductGroup

A wrapper around an implementation of a HashMap, with values of f64.

PwlCurve

A representation of a piecewise-linear, weakly monotone decreasing demand curve

PwlCurveDto

DTO to ensure that we always validate when we deserialize from an untrusted source

ValueRecord

A timestamped record of a component of a user’s bid.

Enums

ConstantCurveError

Errors that can occur when creating or validating a ConstantCurve

DemandCurve

A demand curve expressing a bidder’s willingness to pay at different rates.

DemandCurveDto

DTO for demand curves to enable validation during deserialization

DemandCurveError

Errors that can occur when constructing demand curves

PwlCurveError

Errors that can occur when creating or validating a PwlCurve
