) (ret []byte, rErr error)

ExecTemplate executes the named templated, returning the generated bytes

type TypeConverter 

type TypeConverter struct {
	LineBuilder
	Helper PackageNameResolver
	// contains filtered or unexported fields
}

TypeConverter can generate a function body that converts two thriftrw FieldGroups from one to another. It's assumed that the converted code operates on two variables, "in" and "out" and that both are a go struct.

func NewTypeConverter 

func NewTypeConverter(h PackageNameResolver, optionalEntries map[string]FieldMapperEntry) *TypeConverter

NewTypeConverter returns *TypeConverter (tc) @optionalEntries contains Entries that already set for tc fromFields entry set in @optionalEntries, tc will not raise error when this entry is required for toFields but missing from fromFields

func (*TypeConverter) GenStructConverter 

func (c *TypeConverter) GenStructConverter(
	fromFields []*compile.FieldSpec,
	toFields []*compile.FieldSpec,
	fieldMap map[string]FieldMapperEntry,
) error

GenStructConverter will add lines to the TypeConverter for mapping from one go struct to another based on two thriftrw.FieldGroups. fieldMap is a may from keys that are the qualified field path names for destination fields (sent to the downstream client) and the entries are source fields (from the incoming request)

type TypedHeader 

type TypedHeader struct {
	Name        string
	TransformTo string
	Field       *compile.FieldSpec
}

TypedHeader is typed header for headers resolved from header schema
