Types ¶
type EIFunction ¶
type EIFunction struct {
// An implementation must be of type:
// `func(context unsafe.Pointer, arguments ...interface{}) interface{}`.
// It represents the real function implementation written in Go.
Implementation interface{}
// The pointer to the cgo function implementation, something
// like `C.foo`.
CgoPointer unsafe.Pointer
// The function implementation signature.
FunctionInputs []EIFunctionValue
// The function implementation signature.
FunctionOutputs []EIFunctionValue
// The namespace of the imported function.
Namespace string
}
EIFunction represents a EI function that gets imported in a constract WASM module.
type EIFunctionReceiver ¶
type EIFunctionReceiver interface {
Namespace(namespace string)
Append(importName string, implementation interface{}, cgoPointer unsafe.Pointer) error
}
EIFunctionReceiver abstracts an EI imports container, where EI functions are registered.
type EIFunctionValue ¶
type EIFunctionValue int
EIFunctionValue represents EI argument types
const ( EIFunctionValueInt32 EIFunctionValue = iota EIFunctionValueInt64 )
type EIFunctions ¶
type EIFunctions struct {
FunctionMap map[string]EIFunction
// Current namespace where to register the import.
CurrentNamespace string
}
EIFunctions holds a collection of EI functions.
func NewEIFunctions ¶
func NewEIFunctions() *EIFunctions
NewEIFunctions constructs a new empty `EIFunctions`.
func (*EIFunctions) Append ¶
func (imports *EIFunctions) Append(importName string, implementation interface{}, cgoPointer unsafe.Pointer) error
Append validates and adds a new imported function to the current structure.
func (*EIFunctions) Namespace ¶
func (imports *EIFunctions) Namespace(namespace string)
Namespace changes the current namespace of the next imported functions.
type ImportedFunctionError ¶
type ImportedFunctionError struct {
// contains filtered or unexported fields
}
ImportedFunctionError represents any kind of errors related to a WebAssembly imported function. It is returned by `Import` or `Imports` functions only.
func NewImportedFunctionError ¶
func NewImportedFunctionError(functionName string, message string) *ImportedFunctionError
NewImportedFunctionError constructs a new `ImportedFunctionError`, where `functionName` is the name of the imported function, and `message` is the error message. If the error message contains `%s`, then this parameter will be replaced by `functionName`.
func (*ImportedFunctionError) Error ¶
func (error *ImportedFunctionError) Error() string
ImportedFunctionError is an actual error. The `Error` function returns the error message.
