Struct KeepAliveHandle 

pub struct KeepAliveHandle { /* private fields */ }

A keep-alive request bound to the lazy-list row it was acquired in. See the module docs.

Implementations

impl KeepAliveHandle

pub fn acquire() -> Option<KeepAliveHandle>

A handle bound to the lazy-list row being built or rebuilt right now — call it from View::build (or rebuild). None outside every lazy list’s row, where keep-alive means nothing. The handle starts holding no request.

pub fn set(&mut self, keep_alive: bool)

Hold (true) or withdraw (false) this handle’s request. Idempotent: a handle counts once however often it is set.

pub fn is_held(&self) -> bool

Whether this handle currently holds a request.

Trait Implementations

impl Drop for KeepAliveHandle

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
