Types

type FieldData

type FieldData struct {
	SourceField   string
	TargetField   string
	Kind          string // "direct", "converter", "nested", "slice"
	ConverterCall string
	NestedCall    string
	SliceCall     string
	HasError      bool
	VarName       string
	NilOrZero     string // "nil" for pointer returns, "Type{}" for value returns
}

FieldData holds data for a single field mapping.

type FileData

type FileData struct {
	PackageName string
	Imports     []ImportEntry
	Functions   []FunctionData
}

FileData holds data for generating a complete file.

type FunctionData

type FunctionData struct {
	Name            string
	SourceType      string
	TargetType      string
	SourceQualified string
	TargetQualified string
	IsPointer       bool
	ReturnsPointer  bool
	HasError        bool
	Fields          []FieldData
}

FunctionData holds data for generating a single function.

type Generator

type Generator struct {
	// contains filtered or unexported fields
}

Generator produces mapper code.

func New

func New(reg *registry.Registry, outputPkg, outputPkgPath, outputPath string) *Generator

New creates a new Generator.

func (*Generator) GenerateFile

func (g *Generator) GenerateFile(mappings []*resolver.Mapping, direction string) ([]byte, error)

GenerateFile generates a complete mapper file for the given mappings.

type ImportEntry

type ImportEntry struct {
	Path  string
	Alias string // empty if no alias needed
}

ImportEntry represents a single import with an optional alias.
