Functions

func Array2DEquals 

func Array2DEquals(a [][]string, b [][]string) bool

Array2DEquals determines whether two 2-dimensional string arrays are identical.

func ArrayEquals 

func ArrayEquals(a []string, b []string) bool

ArrayEquals determines whether two string arrays are identical.

func ArrayRemoveDuplicates 

func ArrayRemoveDuplicates(s *[]string)

ArrayRemoveDuplicates removes any duplicated elements in a string array.

func ArrayToString 

func ArrayToString(s []string) string

ArrayToString gets a printable string for a string array.

func EscapeAssertion 

func EscapeAssertion(s string) string

EscapeAssertion escapes the dots in the assertion, because the expression evaluation doesn't support such variable names.

func EscapeStringLiterals added in v1.10.2 

func EscapeStringLiterals(expr string) string

EscapeStringLiterals escapes backslashes in string literals within an expression to ensure consistent handling between govaluate (which interprets escape sequences) and CSV parsing (which treats backslashes as literal characters). This function doubles all backslashes within single-quoted and double-quoted strings.

func GenerateConditionalGFunction added in v1.10.0 

func GenerateConditionalGFunction(crm rbac.ConditionalRoleManager) govaluate.ExpressionFunction
