Struct ConditionId

Source 
pub struct ConditionId {
    private_use_as_methods_instead: u32,
}
Expand description

ID of a mcdc condition. Used by llvm to check mcdc coverage.

Note for future: the max limit of 0xFFFF is probably too loose. Actually llvm does not support decisions with too many conditions (7 and more at LLVM 18 while may be hundreds at 19) and represents it with int16_t. This max value may be changed once we could figure out an accurate limit.
