Types

type Builder

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

Builder builds encoder based on data

func NewEncoderBuilder

func NewEncoderBuilder(resolver yaml.Resolver, compiler Compiler, skipUnknown bool) *Builder

NewEncoderBuilder creates an EncoderBuilder.

func (Builder) Build

func (c Builder) Build(msgName string, data map[string]interface{}) (Encoder, error)

Build builds an Encoder

type Compiler

type Compiler interface {
	// Compile creates a compiled expression from a string expression
	Compile(expr string) (compiled.Expression, v1beta1.ValueType, error)
}

Compiler creates a compiled expression from a string expression

type Encoder

type Encoder interface {
	Encode(bag attribute.Bag, ba []byte) ([]byte, error)
}

Encoder transforms yaml/json that represents protobuf data into []byte String values (rvalues) are treated as expressions that are evaluated using attribute bag at runtime. Quoted String values are treated as literals.

func BuildPrimitiveEncoder

func BuildPrimitiveEncoder(v interface{}, fld *descriptor.FieldDescriptorProto) (Encoder, error)

BuildPrimitiveEncoder encodes the given data and returns a static encoder.

func BuildPrimitiveEvalEncoder

func BuildPrimitiveEvalEncoder(expr compiled.Expression, vt v1beta1.ValueType, fld *descriptor.FieldDescriptorProto) (Encoder, error)

BuildPrimitiveEvalEncoder returns an eval encoder given an expression and a target fieldEncoder

type NamedEncoderBuilderFunc

type NamedEncoderBuilderFunc func(m *descriptor.DescriptorProto, fd *descriptor.FieldDescriptorProto, v interface{}, compiler Compiler) (Encoder, error)

NamedEncoderBuilderFunc funcs have a special way to process input for encoding specific types for example istio...Value field accepts user input in a specific way
