Struct HandshakeResponse 

pub struct HandshakeResponse {
    pub accepted: bool,
    pub protocol_version: u32,
    pub schema_version: u64,
    pub server_id: String,
    pub capabilities: Vec<String>,
    pub error: Option<String>,
}

Server response to a client handshake.

Fields

accepted: bool

Whether the handshake was accepted.

protocol_version: u32

Protocol version the server will use for this connection.

schema_version: u64

Current schema version on the server.

server_id: String

Server identifier.

capabilities: Vec<String>

Capabilities the server supports.

error: Option<String>

Error message if handshake was rejected.

Implementations

impl HandshakeResponse

pub fn accept( protocol_version: u32, schema_version: u64, server_id: impl Into<String>, ) -> Self

Create a successful handshake response.

pub fn reject(error: impl Into<String>) -> Self

Create a rejected handshake response.

pub fn with_capability(self, capability: impl Into<String>) -> Self

Add a capability to the response.

pub fn with_capabilities(self, capabilities: Vec<String>) -> Self

Add multiple capabilities to the response.

Trait Implementations

impl Archive for HandshakeResponse

where bool: Archive, u32: Archive, u64: Archive, String: Archive, Vec<String>: Archive, Option<String>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedHandshakeResponse

The archived representation of this type.

type Resolver = HandshakeResponseResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for HandshakeResponse

fn clone(&self) -> HandshakeResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandshakeResponse

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<HandshakeResponse, __D> for Archived<HandshakeResponse>

where bool: Archive, <bool as Archive>::Archived: Deserialize<bool, __D>, u32: Archive, <u32 as Archive>::Archived: Deserialize<u32, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, String: Archive, <String as Archive>::Archived: Deserialize<String, __D>, Vec<String>: Archive, <Vec<String> as Archive>::Archived: Deserialize<Vec<String>, __D>, Option<String>: Archive, <Option<String> as Archive>::Archived: Deserialize<Option<String>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<HandshakeResponse, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for HandshakeResponse

fn eq(&self, other: &HandshakeResponse) -> 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<__S: Fallible + ?Sized> Serialize<__S> for HandshakeResponse

where bool: Serialize<__S>, u32: Serialize<__S>, u64: Serialize<__S>, String: Serialize<__S>, Vec<String>: Serialize<__S>, Option<String>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
