Struct ProtocolVersion 

pub struct ProtocolVersion {
    pub major: u16,
    pub minor: u16,
}

Protocol version negotiated during the connection handshake.

Fields

major: u16

Major protocol version component.

minor: u16

Minor protocol version component.

Implementations

impl ProtocolVersion

pub const WIRE_LEN: usize = 4

Number of bytes used by a serialized protocol version.

pub const fn new(major: u16, minor: u16) -> Self

Create a protocol version from its major and minor components.

pub const fn serialize(self) -> [u8; 4]

Serialize this version as big-endian major followed by big-endian minor.

pub const fn to_wire_bytes(self) -> [u8; 4]

Serialize this version for wire transport.

pub fn deserialize(bytes: &[u8]) -> Result<Self, ProtocolError>

Deserialize a protocol version from wire bytes.

Errors

Returns ProtocolError::CodecError when bytes is not exactly four bytes long.

pub fn from_wire_bytes(bytes: &[u8]) -> Result<Self, ProtocolError>

Deserialize a protocol version from wire bytes.

Errors

Returns ProtocolError::CodecError when bytes is not exactly four bytes long.

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

Formats the value using the given formatter.

impl Eq for ProtocolVersion

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.
