SuspenseContext

Struct SuspenseContext 

Source
pub struct SuspenseContext { /* private fields */ }
Expand description

The context with which you can create suspense boundaries for futures.

Implementations§

Source§

impl SuspenseContext

Source

pub fn suspend<F, Fut, M>(&self, f: F, placeholder: impl Into<Html>) -> Suspense
where F: FnOnce(SuspenseContext) -> Fut, Fut: Future<Output = M> + Send + 'static, M: Into<Html> + 'static,

Suspends async work and streams the result. This function takes a closure that returns a future, allowing the future to spawn more suspensions. The placeholder is sent immediately, while the future output is streamed and replaces the placeholder in the browser.

The future can return any type that implements Into<Html>, including String, &str, or types like maud::Markup.

Suspended futures must be Send because they are handed to tokio.

Source

pub async fn cancelled(&self)

Yields if SuspendedResponse or the resulting stream type is dropped.

Useful for exiting from suspended futures that should stop if the connection is dropped. Suspended futures are not aborted otherwise, so they will continue to execute if you don’t listen for cancellation.

Source

pub fn is_cancelled(&self) -> bool

Returns true if SuspendedResponse or the resulting stream type is dropped.

Useful for exiting from suspended futures that should stop if the connection is dropped. Suspended futures are not aborted otherwise, so they will continue to execute if you don’t listen for cancellation.
