func LogFatal

func LogFatal(err error, msg string, depth ...int)

LogFatal logs critical errors and terminates the application.

func LogInfo

func LogInfo(format string, args ...interface{})

LogInfo logs an informational message with formatting options.

func ParseHexSubstring

func ParseHexSubstring(hexStr string, byteOffset, byteLength int) (int, int, error)

parseHexSubstring extracts an integer value from a specified hex substring within a larger hex string, based on the offset and length in bytes.

func ParseHexSubstringBigInt

func ParseHexSubstringBigInt(hexStr string, byteOffset, byteLength int) (*big.Int, int, error)

ParseHexSubstringBigInt extracts a large integer value from a specified hex substring within a larger hex string, based on the offset and length in bytes, returning *big.Int.

func ParseHexToASCIIString

func ParseHexToASCIIString(hexStr string, byteOffset int, byteLength int) (string, int, error)

ParseHexToASCIIString converts a segment of a hex string starting at byteOffset for byteLength bytes into its ASCII string representation.

func PrettyPrintJSON

func PrettyPrintJSON(data any)

PrettyPrintJSON takes any data and prints it in an indented JSON format

func RespondWithError

func RespondWithError(w http.ResponseWriter, err error, message string, statusCode int, depth ...int)

RespondWithError logs the error, captures file/line, and sends a detailed error response.

func Splice

func Splice[T any](slice []T, start, count int, elementsToAdd []T) ([]T, []T)

Splice function to remove and optionally add elements to a slice.

func SplitIntoPairs

func SplitIntoPairs(input string) []string

splitIntoPairs splits a string into pairs of two characters.

func StopLogging

func StopLogging()

StopLogging stops the periodic flushing and closes log files.

func StructSliceToMapSlice

func StructSliceToMapSlice(slice any) ([]map[string]any, error)

StructSliceToMapSlice converts a slice of structs into a slice of map[string]any.

func StructToMap

func StructToMap(v any) (map[string]any, error)

StructToMap converts a struct to a map[string]any using JSON marshaling and unmarshaling.

func WrapError

func WrapError(err error) error

Helper function to wrap error with colored file and line context
