Struct RangeLex 

pub struct RangeLex {
    pub min: Vec<u8>,
    pub max: Vec<u8>,
    pub minex: bool,
    pub maxex: bool,
    pub min_infinite: bool,
    pub max_infinite: bool,
    pub offset: usize,
    pub count: Option<usize>,
    pub reversed: bool,
}

Lexicographical range specification (aligned with Apache Kvrocks RangeLex). 字典序范围规格（对标 Apache Kvrocks RangeLex，统一用于 ZSet + Hash）

Fields

min: Vec<u8>

max: Vec<u8>

minex: bool

maxex: bool

min_infinite: bool

max_infinite: bool

offset: usize

count: Option<usize>

reversed: bool

Implementations

impl RangeLex

pub fn new(min: impl Into<Vec<u8>>, max: impl Into<Vec<u8>>) -> Self

pub fn unbounded() -> Self

pub fn is_empty(&self) -> bool

pub fn check(&self, member: &[u8]) -> bool

pub fn from_bounds( min_bound: &[u8], max_bound: &[u8], offset: usize, count: Option<usize>, ) -> Result<Self>

Constructs RangeLex from Redis boundary string with strict validation. 从 Redis 边界字符串或字节切片构造 RangeLex（严格校验 min 为 -/(/[，max 为 +/(/[）

pub fn parse_min_bound(bound: &[u8]) -> Result<(Vec<u8>, bool, bool)>

Parses Redis lexicographical lower bound (valid min is “-” or starts with ‘(’ / ‘[’). 解析 Redis 字典序下界（合法的 min 为 “-” 或以 ‘(’ / ‘[’ 开头）

pub fn parse_max_bound(bound: &[u8]) -> Result<(Vec<u8>, bool, bool)>

Parses Redis lexicographical upper bound (valid max is “+” or starts with ‘(’ / ‘[’). 解析 Redis 字典序上界（合法的 max 为 “+” 或以 ‘(’ / ‘[’ 开头）

pub fn parse_bound(bound: &[u8]) -> Result<(Vec<u8>, bool, bool)>

Parses generic Redis lexicographical boundary (supports “-”, “+”, “(abc”, “[abc”). 通用解析 Redis 字典序边界（支持 “-”, “+”, “(abc”, “[abc”）
