clone

Documentation

Overview

Package clone contains the implementation of the clone plugin, which generates the deriveClone function.

The deriveClone function is a maintainable and fast way to implement fast"ish" clone functions.

func deriveClone(T) T

I say fast"ish", since deriveClone creates a totally new copy of the value, whereas deepcopy reuses as much as of the memory that has been allocated by the destintation value.

Supported types:

• basic types
• named structs
• slices
• maps
• pointers to these types
• private fields of structs in external packages (using reflect and unsafe)
• and many more

Unsupported types:

• chan
• interface
• function
• unnamed structs, which are not comparable with the == operator

Functions

func New

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

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

func NewPlugin

func NewPlugin() derive.Plugin

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