pub struct Scope { /* private fields */ }

Implementations§

Source§

impl Scope

Source

pub fn new() -> Self

Source

pub fn run<R>(&self, f: impl FnOnce() -> R) -> R

Source

pub fn add_disposer(&self, disposer: impl FnOnce() + 'static)

Source

pub fn memo<T: 'static>(&self, key: &str, init: impl FnOnce() -> T) -> Rc<T>

Returns a cached value from this scope’s memo cache, or creates it with init and stores it. The value persists for the lifetime of this scope (i.e., until the scope key is no longer composed or the root is replaced).

Source

pub fn child(&self) -> Scope

Source

pub fn dispose(self)
