Struct PartialUpdates 

pub struct PartialUpdates<H> { /* private fields */ }

Available on crate feature html only.

A streaming HTML response that fills <?marker name="…"> placeholders out-of-order as fragment futures complete.

Pair the shell with crate::protocols::html::marker to emit the processing instructions; this response wraps each fragment’s rendered HTML in a <template for="name">…</template> block as it resolves.

Implementations

impl<H: IntoHtml> PartialUpdates<H>

pub fn new(shell: H) -> Self

Wrap an HTML shell for streaming.

pub fn fragment<F, T>(self, name: &'static str, fut: F) -> Self

where F: Future<Output = T> + Send + 'static, T: IntoHtml + Send + 'static,

Add a fragment whose rendered HTML will be flushed inside a <template for="name">…</template> block once fut resolves.

Whatever the future yields is rendered through IntoHtml — i.e. scalar strings are HTML-escaped, PreEscaped passes through verbatim, and macro-built nodes compose normally.

pub fn try_fragment<F, T, E>(self, name: &'static str, fut: F) -> Self

where F: Future<Output = Result<T, E>> + Send + 'static, T: IntoHtml + Send + 'static, E: Into<BoxError> + Send + 'static,

Like Self::fragment but the future returns a Result; on Err the body stream terminates with that error.

fn into_response(self) -> Response
