Struct BindingContext 

pub struct BindingContext { /* private fields */ }

Represents a binding context. Binding contexts are per-thread structures, used to track which bindings have been accessed in a computed() function.

Implementations

impl BindingContext

pub fn current() -> Option<BindingContext>

Gets the active binding context

pub fn panic_if_in_binding_context(msg: &str)

Panics if we’re trying to create a binding, with a particular message

pub fn bind<TResult, TFn>(to_do: TFn) -> (TResult, BindingDependencies)

where TFn: FnOnce() -> TResult,

Executes a function in a new binding context

pub fn out_of_context<TResult, TFn>(to_do: TFn) -> TResult

where TFn: FnOnce() -> TResult,

Performs an action outside of the binding context (dependencies will not be tracked for anything the supplied function does)

pub fn add_dependency<TChangeable: Changeable + 'static>( dependency: TChangeable, )

Adds a dependency to the current context (if one is found)

Trait Implementations

impl Clone for BindingContext

fn clone(&self) -> BindingContext

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
