Struct SubprotocolVersion 

pub struct SubprotocolVersion {
    pub major: u8,
    pub minor: u8,
}

Semantic version for subprotocol negotiation.

Two peers are compatible if both peers’ version >= the other’s min_compatible. Wire format: 2 bytes (major, minor).

Fields

major: u8

Major version — breaking changes increment this.

minor: u8

Minor version — backward-compatible changes.

Implementations

impl SubprotocolVersion

pub const fn new(major: u8, minor: u8) -> Self

Create a new version.

pub fn satisfies(self, min_required: Self) -> bool

Check if this version is compatible with a peer’s minimum requirement.

pub fn to_bytes(self) -> [u8; 2]

Serialize to 2 bytes.

pub fn from_bytes(data: &[u8; 2]) -> Self

Deserialize from 2 bytes.

Trait Implementations

impl Clone for SubprotocolVersion

fn clone(&self) -> SubprotocolVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SubprotocolVersion

impl Debug for SubprotocolVersion

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

Formats the value using the given formatter.

impl Display for SubprotocolVersion

impl Eq for SubprotocolVersion

impl Hash for SubprotocolVersion

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 SubprotocolVersion

fn cmp(&self, other: &SubprotocolVersion) -> 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 SubprotocolVersion

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

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