Struct Service 

pub struct Service { /* private fields */ }

Available on crate feature p3 only.

Bindings to the wasi:http/service world. Auto-generated bindings for an instance a component which implements the world service.

This structure can be created through a number of means depending on your requirements and what you have on hand:

• The most convenient way is to use Service::instantiate which only needs a Store, Component, and Linker.

• Alternatively you can create a ServicePre ahead of time with a Component to front-load string lookups of exports once instead of per-instantiation. This method then uses ServicePre::instantiate to create a Service.

• If you’ve instantiated the instance yourself already then you can use Service::new.

These methods are all equivalent to one another and move around the tradeoff of what work is performed when.

Implementations

impl Service

pub fn instantiate<_T>( store: impl AsContextMut<Data = _T>, component: &Component, linker: &Linker<_T>, ) -> Result<Service>

Convenience wrapper around ServicePre::new and ServicePre::instantiate.

pub fn new(store: impl AsContextMut, instance: &Instance) -> Result<Service>

Convenience wrapper around ServiceIndices::new and ServiceIndices::load.

pub async fn instantiate_async<_T>( store: impl AsContextMut<Data = _T>, component: &Component, linker: &Linker<_T>, ) -> Result<Service>

where _T: Send,

Convenience wrapper around ServicePre::new and ServicePre::instantiate_async.

pub fn add_to_linker<T, D>( linker: &mut Linker<T>, options: &LinkOptions, host_getter: fn(&mut T) -> D::Data<'_>, ) -> Result<()>

where D: HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + HostWithStore + Send, for<'a> D::Data<'a>: Host + Host + Host + Host + Host + Host + Host + Host + Host + Host + Host + Host + Host + Send, T: 'static + Send,

pub fn wasi_http_handler(&self) -> &Guest

impl Service

pub async fn handle( &self, store: &Accessor<impl WasiHttpView>, req: impl Into<Request>, ) -> Result<Result<(Response, TaskExit), ErrorCode>>

Call wasi:http/handler#handle on Service getting a Response back.
