Functions

func ForEachRange

func ForEachRange(totalSize int, maxSubRangeSize int, handler func(from, to int) error) error

ForEachRange is simple utility calling given function for each sub-range defined within [0-totalSize]. It wont be called however if range is empty. For example, MakeRanges(35, 10, fc) will result in fc being called 4 times with arguments: * 0-10 * 10-20 * 20-30 * 30-35 It can be used to split slice into smaller ones. Params totalSize must not be less than 0, maxSubRangeSize must be bigger than 0. If those are not met, function panics. If given function returns error, iteration stops and ForEachRange returns that error

func GetFieldTypeForOneOf

func GetFieldTypeForOneOf(protoMsg proto.Message, fieldDesc preflect.FieldDescriptor) (reflect.StructField, bool)

func GetValueFromProtoPath

func GetValueFromProtoPath(msg proto.Message, rawPath string) (interface{}, bool)

func GetValuesFromProtoPath

func GetValuesFromProtoPath(msg proto.Message, rawPath string) ([]interface{}, bool, error)

func IsNil

func IsNil(v interface{}) bool

func JsonMarshal

func JsonMarshal(v interface{}) ([]byte, error)

func SetFieldPathValueToProtoMsg

func SetFieldPathValueToProtoMsg(target proto.Message, rawPath string, v any)

func SetFieldValueToProtoMsg

func SetFieldValueToProtoMsg(target proto.Message, fieldDesc preflect.FieldDescriptor, v any)

func ToProtoCase

func ToProtoCase(name string) string

ToProtoCase Converts name to proto convention (replacing capital letters with _ and lowercase letter). No special treatment for digits.
