Struct ErrorLayer 

pub struct ErrorLayer<'a, F> { /* private fields */ }

Available on crate feature error only.

A layer that randomly trigger errors for the service.

This trigger errors based on the given probability and using a function to generate errors.

Implementations

impl<'a, F> ErrorLayer<'a, F>

pub fn new(probability: f64, func: F) -> Result<Self, Error>

Create a new ErrorLayer with the given probability and error function.

The probability is the chance that a request will result in an error, bound between 0 and 1. A probability of 0.5 means that 50% of the calls to the service will result in an error.

Trait Implementations

impl<'a, F: Clone> Clone for ErrorLayer<'a, F>

fn clone(&self) -> ErrorLayer<'a, F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, F: Debug> Debug for ErrorLayer<'a, F>

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

Formats the value using the given formatter.

impl<'a, F, S> Layer<S> for ErrorLayer<'a, F>

where F: Clone,

type Service = ErrorService<'a, F, S>

The wrapped service

fn layer(&self, inner: S) -> Self::Service

Wrap the given service with the middleware, returning a new service that has been decorated with the middleware.
