Overview

Package compose contains the implementation of the compose plugin, which generates the deriveCompose function.

The deriveCompose function composes multiple functions that return an error into one function.

deriveCompose(func() (A, error), func(A) (B, error)) func() (B, error)
deriveCompose(func(A) (B, error), func(B) (C, error)) func(A) (C, error)
deriveCompose(func(A...) (B..., error), func(B...) (C..., error)) func(A...) (C..., error)
deriveCompose(func(A...) (B..., error), ..., func(C...) (D..., error)) func(A...) (D..., error)

Functions

func New

func New(typesMap derive.TypesMap, p derive.Printer, deps map[string]derive.Dependency) derive.Generator

New is a constructor for the compose code generator. This generator should be reconstructed for each package.

func NewPlugin

func NewPlugin() derive.Plugin

NewPlugin creates a new compose plugin. This function returns the plugin name, default prefix and a constructor for the compose code generator.
