Overview

Package af contains a set of adapative functions.

Example (Coalesce) 
package main

import (
	"fmt"

	"github.com/spatialcurrent/go-adaptive-functions/pkg/af"
)

func main() {
	out, err := af.Coalesce.ValidateRun(nil, "", "foo")
	if err != nil {
		panic(err)
	}
	fmt.Printf("%#v\n", out)
}

Output:

"foo"

Types

type Definition 

type Definition struct {
	Inputs []interface{} // an array of types or kinds
	Output interface{}   // the type or kind returned by the defined function
}

Definition is a struct containing a function definition

func (Definition) IsValid 

func (d Definition) IsValid(args ...interface{}) bool

IsValid returns true if the args match the kinds or types or the definition.

type ErrInvalidArguments 

type ErrInvalidArguments struct {
	Function  string        // the name of the Function
	Arguments []interface{} // the arguments for the function
}

ErrInvalidArguments is an error returned when a function is called with invalid arguments.

func (ErrInvalidArguments) Error 

func (e ErrInvalidArguments) Error() string

Error returns the error as a string.

type ErrInvalidCapacity 

type ErrInvalidCapacity struct {
	Value  int
	Length int
}

ErrInvalidCapacity is an error returned when the capacity for a slice is too low since it must always be greater than or equal to the length.

func (ErrInvalidCapacity) Error 

func (e ErrInvalidCapacity) Error() string

Error returns the error as a string.

type ErrOutOfRange 

type ErrOutOfRange struct {
	Index int
	Max   int
}

ErrOutOfRange is an error returned when an array or slice index is out of range.

func (ErrOutOfRange) Error 

func (e ErrOutOfRange) Error() string

Error returns the error as a string.

type ErrOverflow 

type ErrOverflow struct {
	Original interface{}  // the original value
	Target   reflect.Type // the target type
}

ErrOverflow is an error returned a number can't be converted to a lower bitsize.

func (ErrOverflow) Error 

func (e ErrOverflow) Error() string

Error returns the error as a string.

type Function 

type Function struct {
	Name        string                                         // the name of the function
	Description string                                         // a description of the function
	Aliases     []string                                       // aliases for the function used when providing a public API
	Definitions []Definition                                   // the definitions of the function
	Function    func(args ...interface{}) (interface{}, error) // the underlying function to execute
}

Function is a struct used for giving an underlying function a name and definitions.

func (Function) IsValid 

func (f Function) IsValid(args ...interface{}) bool

IsValid returns true if the arguments match a definition of the function.

func (Function) Map 

func (f Function) Map() map[string]interface{}

Map returns a map of metadata about the function.

func (Function) MustRun 

func (f Function) MustRun(args ...interface{}) interface{}

MustRun executes the function with the provided arguments and returns the result. If there is any error, then panics.

func (Function) Run 

func (f Function) Run(args ...interface{}) (interface{}, error)

Run executes the function with the provided arguments and returns the result, and error if any. It accepts variadic input.

func (Function) Validate 

func (f Function) Validate(args ...interface{}) error

Validate returns a ErrInvalidArguments error if the arguments do not match a definition of the function.

func (Function) ValidateRun 

func (f Function) ValidateRun(args ...interface{}) (interface{}, error)

ValidateRun validates the function arguments and then runs the function if valid. It accepts variadic input.

type TestCase struct {
	Inputs   []interface{} // the inputs to the function
	Function Function      // the function to evaluate
	Output   interface{}   // the result of the evaluation
}
