Functions

func EffectiveImportAlias

func EffectiveImportAlias(item gwdkir.Import) (string, error)

EffectiveImportAlias returns the explicit import alias or the package name used by Go for an unaliased import.

func ImportPathForAlias

func ImportPathForAlias(imports []gwdkir.Import, alias string) (string, error)

ImportPathForAlias returns the concrete Go import path for a .gwdk import alias and rejects relative import paths.

func RunStateInitJSON

func RunStateInitJSON(imports []gwdkir.Import, state gwdkir.StateContract) ([]byte, error)

RunStateInitJSON runs a declared state init function and returns its JSON encoding.

func ValidateImportPath

func ValidateImportPath(importPath string) error

ValidateImportPath rejects relative or malformed import paths in component contracts.

func ValidateStateInit

func ValidateStateInit(imports []gwdkir.Import, state gwdkir.StateContract) error

ValidateStateInit verifies that the state init function can initialize the declared state type.

Types

type Field

type Field struct {
	Name string
	Type string
}

Field describes one resolved Go struct field.

type Struct

type Struct struct {
	ImportPath string
	Name       string
	Fields     []Field
	FieldTypes map[string]string
}

Struct describes a resolved Go struct type.

func ResolveStruct

func ResolveStruct(imports []gwdkir.Import, ref gwdkir.GoRef) (Struct, error)

ResolveStruct resolves a Go struct type referenced by a component contract.

func (Struct) FieldNames

func (item Struct) FieldNames() []string

FieldNames returns the resolved struct fields in source/type-checker order.

func (Struct) HasField

func (item Struct) HasField(field string) bool

HasField reports whether the resolved struct declares field.
