Manager of supported API versions for a broker

Implementations

impl ConnectionManager

pub fn builder(broker: Url) -> Builder

Build a manager with a broker endpoint

pub fn client_id(&self) -> Option<String>

Client id used in requests to the broker

pub fn api_version(&self, api_key: i16) -> Result<i16, Error>

The version supported by the broker for a given api key

Trait Implementations

impl Clone for ConnectionManager

fn clone(&self) -> ConnectionManager

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionManager

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

Formats the value using the given formatter.

impl Hash for ConnectionManager

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 Manager for ConnectionManager

type Type = Connection

Type of super::Objects that this Manager creates and recycles.

type Error = Error

Error that this Manager can return when creating and/or recycling super::Objects.

async fn create(&self) -> Result<Self::Type, Self::Error>

Creates a new instance of Manager::Type.

async fn recycle( &self, obj: &mut Self::Type, metrics: &Metrics, ) -> RecycleResult<Self::Error>

Tries to recycle an instance of Manager::Type.

fn detach(&self, _obj: &mut Self::Type)

Detaches an instance of Manager::Type from this Manager.

impl Ord for ConnectionManager

fn cmp(&self, other: &ConnectionManager) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ConnectionManager

fn eq(&self, other: &ConnectionManager) -> 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 PartialOrd for ConnectionManager

fn partial_cmp(&self, other: &ConnectionManager) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
