Functions

func Await

func Await(promise js.Value) (js.Value, error)

Await synchronizes the input promise.

func Call

func Call(obj js.Value, method string, args ...any) (js.Value, error)

Call is the method variant of Invoke.

func Copy

func Copy(dst Bytes, src Bytes)

func Invoke

func Invoke(fn js.Value, args ...any) (js.Value, error)

Invoke exectues a function call, catching a thrown exception and returning it as a Go error.

func Keys

func Keys(obj js.Value) []string

Keys returns the keys of a JS object.

func New

func New(class js.Value, args ...any) (js.Value, error)

func Print

func Print(v js.Value)

Print uses the console.log function to print JS values.

Types

type Bytes

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

Bytes mimics []byte using a JS Uint8Array as the underlying array.

func BytesMake

func BytesMake(length, capacity int) Bytes

func BytesOf

func BytesOf(b []byte) Bytes

func View

func View(arrayBuffer js.Value) Bytes

func (Bytes) Append

func (x Bytes) Append(b []byte) Bytes

func (Bytes) Cap

func (x Bytes) Cap() int

func (Bytes) CopyFrom

func (x Bytes) CopyFrom(b []byte) int

func (Bytes) CopyTo

func (x Bytes) CopyTo(b []byte) int

func (Bytes) Js

func (x Bytes) Js() js.Value

func (Bytes) Len

func (x Bytes) Len() int

func (Bytes) Slice

func (x Bytes) Slice(start, end int) Bytes

type BytesReader

type BytesReader struct {
	Src Bytes
}

BytesReader wraps a Bytes object to function as an io.Reader. [Src] must be a valid Bytes value. It can be retrieved or exchanged when done, and will always be the remaining subslice of the initial data.

func (*BytesReader) Close

func (x *BytesReader) Close() error

func (*BytesReader) Read

func (x *BytesReader) Read(b []byte) (int, error)

type BytesWriter

type BytesWriter struct {
	Dst Bytes
}

BytesWriter wraps a Bytes object to function as an io.Writer. [Dst] must be a valid Bytes value. It may be freely retrieved or exchanged when done writing to the current value.

func (*BytesWriter) Close

func (x *BytesWriter) Close() error

func (*BytesWriter) Write

func (x *BytesWriter) Write(b []byte) (int, error)

type Ticker

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

A Ticker represents a JS Interval. Useful to synchronize with the main JS thread.

func TickerMake

func TickerMake(ms uint64, fn func()) Ticker

func (Ticker) Stop

func (x Ticker) Stop()

Stop disables the Ticker. Must be called from event loop.

type Timer

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

A Timer represents a JS Timeout. Useful to synchronize with the main JS thread.

func TimerMake

func TimerMake(ms uint64, fn func()) Timer

func (Timer) Stop

func (x Timer) Stop()

Stop prevents the Timer from firing, if it has not already done so. Must be called from event loop.
