Struct InverseProportionalConfig

Source 
pub struct InverseProportionalConfig<F>
where
    F: FixedPointNumber,
{
    pub k: F,
    pub epsilon: F,
}
Expand description

Defines the configuration for the InverseProportionalPayout model.

This struct specifies the parameters for an inverse proportional reward function, where rewards decrease as the input increases.

Concept: Inverse Scaling Function

Rewards follow an inverse relationship:

reward = k / (x + eps)

where:

  • k = proportionality constant (scaling factor)
  • x = input variable (e.g., stake, time, or score)
  • eps = small positive constant to prevent division by zero

This model produces high rewards for small inputs and diminishing rewards as input increases.

Fields§

§k: F

Proportionality constant (k): controls overall reward scale

§epsilon: F

Small constant (eps): prevents division by zero and stabilizes behavior near x = 0

impl<T, Time> Logging<Time> for T
where Time: Time,

Source§

const FALLBACK_TARGET: &'static str = "routine"

Default logging target if none is provided.

Most routines, especially offchain workers or background tasks, use this target for simplicity.

It allows a consistent place to look for routine logs without requiring every call to specify a target.

Note: This target is only a conveninence and may be somewhat vague. To ensure errors can still be traced accurately, the logged messages should include additional metadata (e.g., module name, error index, or contextual info) so that the source of the error can be identified even if the target is generic.

Source§

type Logger = DispatchError

The type taken and returned for logging.

We simply return the same [DispatchError] that was logged, so logging does not change control flow or error propagation.

DispatchError is used because in Substrate it encompasses all runtime errors - including module errors, token errors, arithmetic issues, and transactional boundaries - making it the universal substrate-side error representation.

Source§

type Level = LogLevel

The log level type.

We use the LogLevel enum to standardize severity levels (Info, Warn, Error, Debug) across all routine logs.

Source§

fn log( level: <T as Logging<Time>>::Level, err: &<T as Logging<Time>>::Logger, timestamp: Time, target: Option<&str>, fmt: Option<fn(Time, &<T as Logging<Time>>::Level, &str, &str) -> String>, ) -> <T as Logging<Time>>::Logger
