With a melon baller scoop out the seeds, and pulp from center of the cumber.
Chop cucumbers up in 1/4 inch slices and set aside.
In a small saucepan with medium heat, melt sugar, salt, and vinegars until sugar and salt are dissolved. About 2 minutes.
Remove from heat and cool.
Toss together cucumber, carrots, cilantro and red onion.
Pour vinegar mixture, Sweet Chili sauce and lime juice over cucumber mixture.
Marinate for a least 1 hour before serving.
Notes
Two things you can change if the marinade is too tangy for you. #1 omit the red wine vinegar and make the rice vinegar 1/2 cup and #2 omit the lime. If you prefer a spicier version try adding red pepper flakes to add some heat.You can use thin slices or spiralize the cucumbers for a different look.
