Struct fastly::Backend

pub struct Backend { /* private fields */ }

A named backend.

This represents a backend associated with a service that we can send requests to, potentially caching the responses received.

Implementations

impl Backend

pub fn from_name(s: &str) -> Result<Self, BackendError>

Get a backend by its name.

This function will return a BackendError if an invalid name was given.

Backend names:

• cannot be empty
• cannot be longer than 255 characters
• cannot ASCII control characters such as '\n' or DELETE.
• cannot contain special Unicode characters
• should only contain visible ASCII characters or spaces

Future versions of this function may return an error if your service does not have a backend with this name.

pub fn name(&self) -> &str

Get the name of this backend.

pub fn into_string(self) -> String

Turn the backend into its name as a string.

Trait Implementations

impl BackendExt for Backend

fn builder(name: impl ToString, target: impl ToString) -> BackendBuilder

Create a new dynamic backend builder.

fn is_healthy(&self) -> Result<BackendHealth, Error>

Return the health of the backend if configured and currently known.

impl Clone for Backend

fn clone(&self) -> Backend

Returns a copy of the value.

const 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 Display for Backend

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

Formats the value using the given formatter.

impl FromStr for Backend

type Err = BackendError

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 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,

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.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Backend> for Backend

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

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

const 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<Backend> for Backend

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

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

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

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

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

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

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

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

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

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