Struct LayerStack 

pub struct LayerStack { /* private fields */ }

A stack of middleware layers

Implementations

impl LayerStack

pub fn new() -> LayerStack

Create a new empty layer stack

pub fn push(&mut self, layer: Box<dyn MiddlewareLayer>)

Add a middleware layer to the stack

Layers are executed in the order they are added (outermost first).

pub fn prepend(&mut self, layer: Box<dyn MiddlewareLayer>)

Add a middleware layer to the beginning of the stack

This layer will be executed first (outermost).

pub fn is_empty(&self) -> bool

Check if the stack is empty

pub fn len(&self) -> usize

Get the number of layers

pub fn execute( &self, req: Request, handler: Arc<dyn Fn(Request) -> Pin<Box<dyn Future<Output = Response<Full<Bytes>>> + Send>> + Sync + Send>, ) -> Pin<Box<dyn Future<Output = Response<Full<Bytes>>> + Send>>

Execute the middleware stack with a final handler

Trait Implementations

impl Clone for LayerStack

fn clone(&self) -> LayerStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for LayerStack

fn default() -> LayerStack

Returns the “default value” for a type.

impl Extend<Box<dyn MiddlewareLayer>> for LayerStack

fn extend<T>(&mut self, iter: T)

where T: IntoIterator<Item = Box<dyn MiddlewareLayer>>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl IntoIterator for LayerStack

type Item = Box<dyn MiddlewareLayer>

The type of the elements being iterated over.

type IntoIter = IntoIter<<LayerStack as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <LayerStack as IntoIterator>::IntoIter

Creates an iterator from a value.
