Struct WireVersion 

pub struct WireVersion {
    pub major: u32,
    pub minor: u32,
    pub patch: u32,
}

Parsed wire protocol version with MAJOR.MINOR.PATCH components.

Use WireVersion::parse or str::parse::<WireVersion>() to create. Use is_compatible to check whether two nodes can cluster together.

Fields

major: u32

Breaking wire format changes.

minor: u32

New optional wire features (backward-compatible).

patch: u32

Bug fixes in serialization (no format change).

Implementations

impl WireVersion

pub fn parse(s: &str) -> Result<Self, ParseWireVersionError>

Parse a "MAJOR.MINOR.PATCH" string into a WireVersion.

Returns an error if the string is not exactly three dot-separated non-negative integers (no whitespace, no extra segments).

pub fn is_compatible(&self, other: &WireVersion) -> bool

Check whether self is compatible with other per the dactor wire-version policy: two versions are compatible if and only if they share the same MAJOR version number.

Trait Implementations

impl Clone for WireVersion

fn clone(&self) -> WireVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WireVersion

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

Formats the value using the given formatter.

impl Display for WireVersion

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

Formats the value using the given formatter.

impl FromStr for WireVersion

type Err = ParseWireVersionError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for WireVersion

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

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 WireVersion

fn cmp(&self, other: &Self) -> 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 WireVersion

fn eq(&self, other: &WireVersion) -> 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 WireVersion

fn partial_cmp(&self, other: &Self) -> 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.
