Trait Operation

pub trait Operation:
    Serialize
    + Clone
    + PartialEq
    + Send
    + 'static {
    type Output: DeserializeOwned + Send + Unpin + 'static;
}

Operation trait links together input and output of a side-effect.

You implement Operation on the payload sent by the capability to the shell using CapabilityContext::request_from_shell.

For example (from crux_http):

impl Operation for HttpRequest {
    type Output = HttpResponse;
}

Required Associated Types

type Output: DeserializeOwned + Send + Unpin + 'static

Output assigns the type this request results in.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl Operation for Never

Implement Operation for Never to allow using it as a capability operation.

type Output = ()

impl Operation for RenderOperation
