Struct VersionHandshake 

pub struct VersionHandshake {
    pub version: (u64, u64, u64),
    pub min_compatible: (u64, u64, u64),
    pub build_id: String,
}

Version handshake exchanged between nodes on initial connection.

Both sides send a VersionHandshake and then call is_compatible_with on the remote side’s handshake before proceeding.

Fields

version: (u64, u64, u64)

The exact version running on the sending node.

min_compatible: (u64, u64, u64)

The oldest version the sending node is willing to talk to.

build_id: String

Stringified semver from CARGO_PKG_VERSION, useful for diagnostics.

Implementations

impl VersionHandshake

pub fn current() -> Self

Construct a handshake that describes this binary.

pub fn is_compatible_with(&self, other: &VersionHandshake) -> bool

Returns true when other is compatible with this node.

The check is intentionally symmetric: each side applies its own local is_compatible rules against the remote version.

Trait Implementations

impl Clone for VersionHandshake

fn clone(&self) -> VersionHandshake

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionHandshake

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VersionHandshake

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for VersionHandshake

impl PartialEq for VersionHandshake

fn eq(&self, other: &VersionHandshake) -> 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 Serialize for VersionHandshake

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
