Enum SecurityProtocol 

#[non_exhaustive]
pub enum SecurityProtocol {
    Plaintext,
    Ssl,
    SaslPlaintext,
    SaslSsl,
}

Defines the security protocol used for communication with Kafka brokers.

Each protocol has a permanent, immutable numeric ID that matches the wire-protocol values used by the Java client.

Translated from org.apache.kafka.common.security.auth.SecurityProtocol.

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.

Plaintext

Un-authenticated, non-encrypted channel.

Ssl

SSL channel.

SaslPlaintext

SASL authenticated, non-encrypted channel.

SaslSsl

SASL authenticated, SSL channel.

Implementations

impl SecurityProtocol

pub fn id(self) -> i16

Returns the permanent and immutable numeric ID for this security protocol.

This value matches kafka.cluster.SecurityProtocol and must never change.

pub fn name(self) -> &'static str

Returns the protocol name as used in configuration (e.g. "PLAINTEXT", "SASL_SSL").

pub fn for_id(id: i16) -> Option<Self>

Looks up a security protocol by its numeric ID.

Returns None if no protocol has the given ID.

pub fn for_name(name: &str) -> Option<Self>

Case-insensitive lookup by protocol name.

Returns None if no protocol matches the given name.

pub fn names() -> Vec<&'static str>

Returns the names of all security protocols.

Trait Implementations

impl Clone for SecurityProtocol

fn clone(&self) -> SecurityProtocol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SecurityProtocol

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

Formats the value using the given formatter.

impl Display for SecurityProtocol

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

Formats the value using the given formatter.

impl FromStr for SecurityProtocol

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

Parses a security protocol from its name (case-insensitive).

type Err = String

The associated error which can be returned from parsing.

impl Hash for SecurityProtocol

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 SecurityProtocol

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