Enum Protocol

#[non_exhaustive]
pub enum Protocol {
    Http(Version),
    Grpc,
    WebSocket,
    Other(String),
}

The transport protocol used for a connection.

This is for informational purposes only, and can be used to select the appropriate transport when a transport should be pre-negotiated (e.g. ALPN or a Duplex socket).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Http(Version)

HTTP transports

Grpc

gRPC

WebSocket

WebSocket

Other(String)

Other protocol

Implementations

impl Protocol

pub fn http(version: Version) -> Self

Create a new protocol with the given http version.

pub fn grpc() -> Self

New gRPC protocol

pub fn web_socket() -> Self

New WebSocket protocol

Trait Implementations

impl Clone for Protocol

fn clone(&self) -> Protocol

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Protocol

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

Formats the value using the given formatter.

impl Display for Protocol

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

Formats the value using the given formatter.

impl From<Version> for Protocol

fn from(version: Version) -> Self

Converts to this type from the input type.

impl FromStr for Protocol

type Err = Infallible

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Protocol

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 PartialEq for Protocol

fn eq(&self, other: &Protocol) -> 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.
