CachedPocketIcBaseline

Struct CachedPocketIcBaseline 

Source 
pub struct CachedPocketIcBaseline<T> { /* private fields */ }
Expand description

One owned PocketIC instance with captured snapshots and caller metadata.

The value contains no global synchronization. Callers choose the specific Mutex slot passed to restore_or_rebuild_cached_pocket_ic_baseline.

Implementations§

Source§

impl<T> CachedPocketIcBaseline<T>

Source

pub fn capture<I>( pocket_ic: PocketIc, controller_id: Principal, canister_ids: I, metadata: T, ) -> Result<Self, ControllerSnapshotError>
where I: IntoIterator<Item = Principal>,

Capture one cached baseline from the current PocketIC instance.

Snapshot capture is ordered and transactional as documented by PocketIcSnapshotExt::capture_controller_snapshots.

Source

pub fn restore( &self, controller_id: Principal, ) -> Result<(), ControllerSnapshotError>

Restore the captured snapshot set without adding cycles.

Source

pub fn restore_with_funding( &self, controller_id: Principal, funding: SnapshotRestoreFunding, ) -> Result<(), ControllerSnapshotError>

Restore the captured snapshot set with an explicit cycle-funding policy.

Source

pub const fn pocket_ic(&self) -> &PocketIc

Borrow the owned PocketIC instance behind this cached baseline.

Source

pub const fn metadata(&self) -> &T

Borrow the captured metadata associated with this cached baseline.

Source

pub const fn metadata_mut(&mut self) -> &mut T

Mutably borrow the captured metadata associated with this cached baseline.
