Function ParseIntValue

pkg/typeutil/convert.go:48–72

ParseIntValue strictly parses numeric types (int, int64, uint64, float64) to int, returning (value, true) on success and (0, false) for any unrecognized or non-numeric type. Use this when the caller needs to distinguish a missing/invalid value from a legitimate zero, or when string inputs are not e

(value any)

// For lenient conversion that also handles string inputs and returns 0 on failure,
// use ConvertToInt instead.
func ParseIntValue(value any) (int, bool) {
	switch v := value.(type) {
	case int:
		return v, true
	case int64:
		return int(v), true
	case uint64:
		// Check for overflow before converting uint64 to int
		const maxInt = int(^uint(0) >> 1)
		if v > uint64(maxInt) {
			typeutilLog.Printf("uint64 value %d exceeds max int value, returning 0", v)
			return 0, false
		}
		return int(v), true
	case float64:
		intVal := int(v)
		// Warn if truncation occurs (value has fractional part)
		if v != float64(intVal) {
			typeutilLog.Printf("Float value %.2f truncated to integer %d", v, intVal)
		}
		return intVal, true
	default:
		return 0, false
	}
}
