Capture
The Decoder.Capture method allows to unread everything is read in callback. This is useful for multi-pass parsing:
func TestDecoder_Capture(t *testing.T) {
d := DecodeString(`["foo", "bar", "baz"]`)
var elems int
if err := d.Capture(func(d *Reader) error {
return d.Arr(func(d *Reader) error {
elems++
return d.Skip()
})
}); err != nil {
t.Fatal(err)
}
// Buffer is rolled back to state before "Capture" call:
require.Equal(t, Array, d.Next())
require.Equal(t, 3, elems)
}
ObjectBytes
The Decoder.ObjectBytes method tries not to allocate memory for keys, reusing existing buffer:
d := DecodeString(`{"id":1,"randomNumber":10}`)
d.ObjectBytes(func(d *Decoder, key []byte) error {
switch string(key) {
case "id":
case "randomNumber":
}
return d.Skip()
})
