Struct pingora_load_balancing::Backend

pub struct Backend {
    pub addr: SocketAddr,
    pub weight: usize,
}

Backend represents a server to proxy or connect to.

Fields

addr: SocketAddr

The address to the backend server.

weight: usize

The relative weight of the server. Load balancing algorithms will proportionally distributed traffic according to this value.

Implementations

impl Backend

pub fn new(addr: &str) -> Result<Self>

Create a new Backend with weight 1. The function will try to parse addr into a std::net::SocketAddr.

Methods from Deref<Target = SocketAddr>

pub fn as_inet(&self) -> Option<&SocketAddr>

Get a reference to the IP socket if it is one

pub fn as_unix(&self) -> Option<&SocketAddr>

Get a reference to the Unix domain socket if it is one

pub fn set_port(&mut self, port: u16)

Set the port if the address is an IP socket.

Trait Implementations

impl Clone for Backend

fn clone(&self) -> Backend

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Backend

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

Formats the value using the given formatter.

impl Deref for Backend

type Target = SocketAddr

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Backend

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Hash for Backend

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 Ord for Backend

fn cmp(&self, other: &Backend) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Backend

fn eq(&self, other: &Backend) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Backend

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl ToSocketAddrs for Backend

type Iter = Once<SocketAddr>

Returned iterator over socket addresses which this type may correspond to.

fn to_socket_addrs(&self) -> Result<Self::Iter>

Converts this object to an iterator of resolved SocketAddrs.

impl Eq for Backend
