Struct ExtensionProtocolVersion 

pub struct ExtensionProtocolVersion {
    pub version: u16,
}

Carries extension protocol version data across a host-port boundary. Constructing the value does not call the host; the port method that receives it documents any adapter, network, or storage effect.

Fields

version: u16

Version string for this capability, package, or protocol surface. Use it for compatibility checks during package or adapter resolution.

Implementations

impl ExtensionProtocolVersion

pub const SUPPORTED_VERSION: u16 = 1

Constant value for the ports::extension contract. Use it to keep SDK records and tests aligned on the same stable value.

pub fn negotiate(version: u16) -> Result<Self, ExtensionProtocolError>

Negotiate. This validates protocol-version compatibility and returns an error before any bridge call when unsupported.

Trait Implementations

impl Clone for ExtensionProtocolVersion

fn clone(&self) -> ExtensionProtocolVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensionProtocolVersion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExtensionProtocolVersion

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ExtensionProtocolVersion

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
