Struct ProtocolVersion 

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

A semantic version triple for a protocol (major.minor.patch).

Ordering follows standard semver lexicographic comparison: major is most significant, then minor, then patch.

Fields

major: u32

minor: u32

patch: u32

Implementations

impl ProtocolVersion

pub fn new(major: u32, minor: u32, patch: u32) -> Self

Construct a new version triple.

pub fn parse(s: &str) -> Option<Self>

Parse a dotted version string such as "1.2.3".

Returns None if the string does not contain exactly three dot-separated numeric components.

pub fn is_compatible_with( &self, other: &Self, min_compatible: &Self, ) -> CompatibilityLevel

Determine the CompatibilityLevel of self (the local version) with respect to other (the remote version), given min_compatible as the oldest version we are willing to speak with.

Rules (evaluated in priority order):

1. other < min_compatible → Incompatible
2. other == self → FullyCompatible
3. other < self → BackwardCompatible (remote is older)
4. other > self → ForwardCompatible (remote is newer)

pub fn to_string_repr(&self) -> String

Return the canonical string representation "major.minor.patch".

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 Debug for ProtocolVersion

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

Formats the value using the given formatter.

impl Display for ProtocolVersion

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

Formats the value using the given formatter.

impl Eq for ProtocolVersion

impl Hash for ProtocolVersion

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 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.
