parseOn method
Primitive method doing the actual parsing.
The method is overridden in concrete subclasses to implement the
parser specific logic. The methods takes a parse context
and
returns the resulting context, which is either a Success or
Failure context.
Implementation
@override
Result<String> parseOn(Context context) {
final buffer = context.buffer;
final position = context.position;
if (position < buffer.length) {
return context.success(buffer[position], position + 1);
}
return context.failure(message);
}
