Struct FromContext

Source
pub struct FromContext<T: Send + Sync + Clone + 'static>(pub T);
Available on crate feature server only.
Expand description

Extract a value from the server context provided through the launch builder context or DioxusServerContext::insert

Example:

use dioxus::prelude::*;

dioxus::LaunchBuilder::new()
    // You can provide context to your whole app (including server functions) with the `with_context` method on the launch builder
    .with_context(server_only! {
        1234567890u32
    })
    .launch(app);

#[server]
async fn read_context() -> Result<u32, ServerFnError> {
    // You can extract values from the server context with the `extract` function
    let FromContext(value) = extract().await?;
    Ok(value)
}

fn app() -> Element {
    let future = use_resource(read_context);
    rsx! {
        h1 { "{future:?}" }
    }
}

Trait Implementations§

Source§

impl<T: Send + Sync + Clone + 'static> FromServerContext for FromContext<T>

Source§

type Rejection = NotFoundInServerContext<T>

The error type returned when extraction fails. This type must implement std::error::Error.
Source§

fn from_request<'life0, 'async_trait>( req: &'life0 DioxusServerContext, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Extract this type from the server context.
