can you elaborate on this check change? Before there was a range check of 5..9 and now everything above 23?

This was changed to reduce the number of checks.

Previously, the special underlines were in the middle of the enum, so you had to check for a lower and an upper bound whenever they came up.

Now, I moved them to the end, so you only have to check for a lower bound.

Hey, just asking real quick, but are there plans for merging this PR? Any other concerns with its contents? I'm asking because I have a crate that depends on my github version, and it is not possible to depend on a github version when publishing to crates.io

23 makes it difficult to work out how this code works and makes the code fragile to changes. Would this work better? It still assumes that the underline types are sequential, but makes it easier to understand what bounds are in play here.

Suggested change
if (self as usize) > 23 {
if (self as usize >= Self::DoubleUnderlined as usize) && (self as usize <= Self::Underdashed as usize) {

return "4:".to_string() + SGR[self as usize].to_string().as_str();
