Struct ConcreteApplierHost 

pub struct ConcreteApplierHost<A: Applier + 'static> { /* private fields */ }

An ApplierHost that stores one applier of the concrete type A.

Implementations

impl<A: Applier + 'static> ConcreteApplierHost<A>

pub fn new(applier: A) -> Self

Creates a host that owns applier.

pub fn borrow_typed(&self) -> ApplierGuard<'_, A>

Borrows the applier mutably with its concrete type. Panics if it is already borrowed.

pub fn try_borrow_typed(&self) -> Result<ApplierGuard<'_, A>, BorrowMutError>

Borrows the applier mutably with its concrete type. Returns an error if it is already borrowed.

pub fn try_into_inner(self) -> Result<A, (Self, NodeError)>

Returns the applier after all queued nodes have been disposed.

On failure, returns this host with its pending resources and the error, allowing the caller to repair the cause and retry extraction.

use cranpose_core::{ConcreteApplierHost, MemoryApplier};
let host = ConcreteApplierHost::new(MemoryApplier::new());
assert!(host.try_into_inner().is_ok());

Trait Implementations

impl<A: Applier + 'static> ApplierHost for ConcreteApplierHost<A>

fn borrow_dyn(&self) -> ApplierGuard<'_, dyn Applier>

Borrows the applier mutably as a trait object. Dropping the guard finishes any node disposal queued while it was held.

fn dispose_nodes(&self, disposal: NodeDisposal) -> Result<(), NodeError>

Disposes detached roots, deferring recursive cleanup to the current borrow’s guard.

fn compact(&self)

Compacts internal storage after commands have been applied.
