Struct CellLoop 

pub struct CellLoop<A> { /* private fields */ }

A forward reference for a Cell for creating dependency loops.

Both the creation of a CellLoop and filling it with the referenced Cell by calling loop_ must occur within the same transaction, whether that is created by calling SodiumCtx::transaction or Transaction::new.

Implementations

impl<A: Send + Clone + 'static> CellLoop<A>

pub fn new(sodium_ctx: &SodiumCtx) -> CellLoop<A>

Create a new CellLoop in the given context.

pub fn cell(&self) -> Cell<A>

Return a Cell that is equivalent to this CellLoop once it has been resolved by calling loop_.

If a Cell created by CellLoop may be passed to an abstraction that uses Cell::sample, then Cell::sample_lazy should be used instead.

pub fn loop_(&self, ca: &Cell<A>)

Resolve the loop to specify what this CellLoop was a forward reference to.

This function must be invoked in the same transaction as the place where the CellLoop was created. This requires creating an explicit transaction, either with SodiumCtx::transaction or Transaction::new.

Trait Implementations

impl<A> Clone for CellLoop<A>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
