I have a method that received a &[u8] that represents a status code and I want to turn it into an enum, so I have a method that matches the slice to the enum. What I'm not sure is the best way to represent the values to match. Which one is cheaper: to convert the value to a String, represent with a byte string literal or as an inlined array?
pub(crate) fn from_slice(slice: &[u8]) -> Option<SqlStateCode> {
match slice {
b"3030303030" => Some(SqlStateCode::SuccessfulCompletion),
b"3031303030" => Some(SqlStateCode::Warning),
b"3031303043" => Some(SqlStateCode::DynamicResultSetsReturned),
_=> None
}
}
