Struct Authentication

pub struct Authentication {
    pub method: String,
    pub data: Vec<u8>,
}

By default, Connect packets provide optional user_name and password fields which can be used to provide basic authentication. Enhanced authentication can be provided by using an Authentication structure which will initialize a challenge / response style authentication. Ii might imply the exchange of several Auth with reason code ContinueAuthentication until eventually one is send with either Success or any relevant error code and, in that case, close the connection. The authentication method which is used as an agreement on how authentication exchanges will perform. Authentication data can be sent at any moment according to this agreement. See the section 4.12 (Enhanced Authentication) of the MQTT 5 specifications for examples.

Fields

method: String

Specifies the authentication method, such as “SCRAM-SHA-1” or “GS2-KRB5”. The actual support for a given authentication method is up to the server. If the server does not support the requested method, it will respond with a Connack packet with reason code NotAuthorized or BadAuthenticationMethod and close the connection.

data: Vec<u8>

Authentication may contains data. The content depends on the authentication method.

Implementations

impl Authentication

pub async fn write<W: AsyncWrite + Unpin>( self, writer: &mut W, ) -> SageResult<usize>

Write authentication data into writer, returning the written size in case of success.

Trait Implementations

impl Clone for Authentication

fn clone(&self) -> Authentication

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Authentication

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

Formats the value using the given formatter.

impl Default for Authentication

fn default() -> Authentication

Returns the “default value” for a type.

impl PartialEq for Authentication

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