Struct ProtocolVersion 

pub struct ProtocolVersion {
    pub major: u64,
    pub minor: u64,
    pub patch: u64,
}

语义化版本三元组 / Semantic version triple (MAJOR.MINOR.PATCH)。

顺序按 (major, minor, patch) 字典序（derive(Ord) 字段声明序），对齐 Python order=True。

Fields

major: u64

主版本号 / major.

minor: u64

次版本号 / minor.

patch: u64

修订号 / patch.

Implementations

impl ProtocolVersion

pub const fn new(major: u64, minor: u64, patch: u64) -> ProtocolVersion

构造版本三元组 / Construct a version triple.

pub fn parse(s: &str) -> Result<ProtocolVersion, ProtocolVersionParseError>

解析 MAJOR.MINOR.PATCH；段数不为 3 或非整数均返回错误。 Parse MAJOR.MINOR.PATCH; not exactly 3 integer parts → error。

严格 3 段：对齐协议 versioning.md 参考实现与 Python version.py——"0.2"（2 段） 视为非法。SDK 暴露的 crate::PROTOCOL_VERSION 恒为 3 段，握手 query 始终传 3 段。

Errors

段数 ≠ 3、含空段或非数字段（含负号 / 溢出 u64）时返回 ProtocolVersionParseError。

Trait Implementations

impl Clone for ProtocolVersion

fn clone(&self) -> ProtocolVersion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ProtocolVersion

impl Debug for ProtocolVersion

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for ProtocolVersion

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

impl Eq for ProtocolVersion

impl FromStr for ProtocolVersion

type Err = ProtocolVersionParseError

The associated error which can be returned from parsing.

fn from_str( s: &str, ) -> Result<ProtocolVersion, <ProtocolVersion as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for ProtocolVersion

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ProtocolVersion

fn cmp(&self, other: &ProtocolVersion) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ProtocolVersion

fn eq(&self, other: &ProtocolVersion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ProtocolVersion

fn partial_cmp(&self, other: &ProtocolVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
