Required Associated Constants

const FUNCTION_TYPE: FunctionType

Required Methods

fn validate_load(x_in: Decimal, y_in: Decimal) -> Result<(Decimal, ValueCode)>

fn eval( fd: &FunctionData, x: Decimal, interp: Interpolation, saturating: bool, ) -> Result<Decimal>

Provided Methods

fn proportion_difference(a: Decimal, b: Decimal) -> Result<Decimal>

fn interpolate( fd: &FunctionData, x: Decimal, interp: Interpolation, ) -> Result<Decimal>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
