Typedefs

ByteReaderSync = int Function(List<int> bytes, [int start, int? end])

Called to read the next portion of bytes from/to file or stdin/stdout (blocking)

ByteWriterSync = void Function(List<int> bytes, [int start, int? end])

Called to write the next portion of bytes from/to file or stdin/stdout (blocking)

UtfBomHandler = void Function(UtfType type, bool isWrite)

Called while reading or writing UTF BOM (always synchronous)

UtfIoHandler = VisitHandler<String>

Called while reading UTF (non-blocking or blocking)

UtfIoHandlerSync = VisitHandlerSync<String>

Called while reading UTF (blocking)

UtfIoParams = VisitParams<String>

Type for read parameters

Exceptions / Errors

UtfException

Base UTF exception (optional)
