Установка и запуск

Installation

go get github.com/IBM/fp-go

Example: Chaining Operations

import (
    "github.com/IBM/fp-go/either"
    "github.com/IBM/fp-go/function"
)

result := function.Pipe3(
    either.Right[error](10),
    either.Map(func(x int) int { return x * 2 }),
    either.Chain(func(x int) either.Either[error, int] {
        if x > 15 {
            return either.Right[error](x)
        }
        return either.Left[int](errors.New("too small"))
    }),
    either.GetOrElse(func() int { return 0 }),
)
