func IsMatchPattern ¶ added in v1.8.0

func IsMatchPattern(pattern string, value string) bool

IsMatchPattern is used to determine whether pattern and value match with wildcards currently supported *

func IsNil ¶

func IsNil(i interface{}) bool

IsNil checks whether the given interface value is nil. It performs a deep nil check by examining both the interface itself and the underlying value using reflection. Returns true if the value is nil or if the underlying value is nil. For non-nilable types (e.g., int, string, struct), it returns false.

func RegSplit ¶ added in v1.3.0

func RegSplit(text string, regexSplit string) []string

RegSplit splits a string by a regular expression pattern. It uses the provided regex pattern to find all split positions in the text and returns a slice of substrings between those positions.

Parameters:

• text: The string to be split
• regexSplit: The regular expression pattern used as delimiter

Returns a slice of strings containing the split results.

Example:

RegSplit("a;b;c", "\\s*[;]+\\s*") returns ["a", "b", "c"]

func Slice ¶ added in v1.11.25

func Slice(s string) []byte

Slice converts a string to a byte slice without memory allocation. It uses unsafe operations to directly reference the underlying string data, avoiding the overhead of copying bytes.

WARNING: This function uses unsafe operations. The returned byte slice shares the same underlying memory as the string. Modifying the returned slice will cause undefined behavior since strings are immutable in Go.

Parameters:

• s: The string to convert

Returns a byte slice that references the string's underlying data.

Use this function only when you need read-only access to string bytes with zero allocation, and you understand the safety implications.
