Functions

func CalculateResourceScore 

func CalculateResourceScore(issues scanner.IssueList) (float64, map[string]int)

CalculateResourceScore calculates the resource score and severity statistics based on the provided issues.

func CalculateScore 

func CalculateScore(p, s int) float64

CalculateScore calculates the score based on the number of issues and their severity sum (in the range of 1-5). P is the number of issues, and S is the sum of the severity (range 1-5) of the issue S will not be less than P.

Example: - When there is one high-level issue, P=1 and S=3. - When there are three high-level issues, P=3 and S=9. - When there are ten low-level issues, P=10 and S=10.

func GetTopResultsFromMap 

func GetTopResultsFromMap(m map[string]int) map[string]int
